I'm looking for a oxycetaline (new)setup, what should I look at?
I am a fan of Smiths.
The torch just feels good in my hands and the quality is top shelf.
A Victor Journeyman is almost the industry standard and you can't go wrong with it.
One factor to consider is what does you LWS support? If you need a tip or parts and can't wait for the brown truck to bring you parts then you need to rely on your LWS.
What ever you decide to buy, just don't get some import knock off of a Victor. There are lots of them out there and when you are dealing with acetylene, cheap is not the way to go.

I think I'm in the minority but I've always used Harris and it works, no complaints.
If you are just heating and cutting go oxy-propane rather than oxy-acetylene. Cheaper fuel but you can't weld with it.
+1 for this one. Make sure you get the correct grade of hose for propane too. That and the tips are not interchangeable.
Flame Tech out of Texas makes excellent outfits. Been around almost 40 years and they have fantastic support and good distribution through LWSs.
If you get into cutting plate they also manufacture an excellent tool called the scorpion ez cut
Grade R and RM hose are for acetylene only (RM has an oil resistant exterior covering). Grade T is rated for all fuel gases, and would be acceptable for propane or acetylene.
From a fuel safety standpoint, acetylene is probably safer indoors than propane. Propane is MUCH cheaper, but it also uses more oxygen, so that cuts into your savings (though cutting uses so much oxygen on its own, that the different may negligible if you don't braze or weld).
Anything is safer than acetylene. Oxypropane is far cheaper than oxyacetylene. Do you know the difference and reason behind the hose drama? I wouldn't worry about hose so much.
While acetylene has all sorts of safety restrictions, it does not pool, since it is lighter than air. Propane cylinders are absolutely not allowed indoors. Acetylene is fine in a basement. Those in the know, will point out that of the gases we deal with, oxygen is probably the most dangerous.
As for the host grade differences, I will quote myself from another site:
Grade R hose is made from rubber (EPDM over EPDM to be specific), which is safe for use with acetylene (and EPDM has a satisfactory service life in the presence of acetone too), but which is NOT safe with propane. Propane (especially if any liquid gets into the hose) will dissolve the rubber from the inside out (so the damage will not be visible until it fails). Grade R hose is also not oil resistant. Oil exposure will destroy it from the outside in. Grade R hose is rated as safe with acetylene only (it will clearly state this on the packaging for good reason).
Grade RM hose uses two layers, with SBR rubber on the inside, and neoprene on the outside. Neoprene is oil resistant, so grade RM hose will hold up a little better in an oily environment, however the SBR rubber is sensitive to acetone (though if used properly, there should never be acetone in your hoses), and also to propane. Again, propane can destroy a grade RM hose from the inside out. While the cover layer is resistant to propane, it is the inner liner layer which is wrapped by the textile that is responsible for holding pressure, so RM hose is not safe with propane, and is rated as safe for acetylene only.
Grade T hose uses two layers of neoprene. This is the ONLY grade of welding hose that is considered safe for all welding gases.
Refer to this chart for propane vs rubber:

Ok, Google works. What temperature does propane turn liquid? It is liquid propane that attacks rubber. It isn't a widespread problem because sane people do not live where such temperatures are possible.
If you think settling of gases is the primary danger from flammable gases, you have not been paying attention. Propane cylinders are commonly used indoors on forklifts, floor polishers, and other equipment. Propane is commonly used for heating indoors also. The reason the cylinders are not allowed inside is because the decision to vent the cylinders to handle thermal expansion was made last century. Most tanks are not designed to constantly leak on purpose like the LPG and relatives.
Explosive decomposition is not a propane problem. Copper is not a catalyst for propane. Propane has a fairly tight flammability limit in air. Propane can be stored in a simple hollow tank. Propane isn't particularly shock sensitive. When propane does pool, it is fairly hard to ignite and often flashes instead of explodes.
Acetylene cannot be stored over about 60 psi. It must be dissolved in acetone which adds it's own problems. Even dissolved it must be dispersed through a porous mass to prevent explosive decomposition from rough handling. Copper can violently catalyze acetylene. Acetylene hose if pressurized to about 50 psi at room temperature can explode if impacted.
It's worst feature is it will burn at very low concentrations or at very high concentrations.
Oxygen isn't even close to the most dangerous gas commonly handled. Chlorine, for example, is worse.
Then everyone here insane. Propane is liquid in the tank. And it is not all that difficult to get liquid propane in your lines. That can happen simply if you shake the tank or tip it while withdrawing gas, but there are other scenarios too. LP is a mix of gases, and butane is often in there. Your line pressures can often be enough to liquify butane, as the pressure inside a Bic lighter isn't all that high.
Propane cylinders are NOT allowed indoors. A warehouse with a forklift may have a roof, but it is far from indoors. Try using a propane powered engine inside an air conditioned facility. There's a reason that places own electric forklifts. Yes, propane is used for indoor heating. Find me a place that will install your cylinder indoors. The same restrictions do not exist for acetylene, for good reason. Propane leaks are known for seeking drains.
Acetylene has an LEL of 2.6 ,and an HEL of 13.
Propane has an LEL of 2.1 and an HEL of 9.5. Butane has an LEL of 1.8.
In a fairly open space, the LEL is MUCH more important than the HEL, and as such, propane is easier to ignite.
Explosive decomposition of acetylene and reaction with copper are easy to avoid if you are able to follow instructions.
Yes, there are countless gases used industrially that are more dangerous than anything used by the people here (and many of those make chlorine look tame). But in the garage environment, the list is pretty short, chlorine is not on that list, and I stand by oxygen being the most dangerous gas we would expect to encounter.
Oops, I forgot to feed the trolls.

sigh. here you are again derailing another thread by starting an argument on a subject that has nothing to do with the original subject matter. (aka: TROLLING)
more than one of us have noticed you are notorious for this. it appears, to the untrained eye, that such efforts are an attempt to somehow make yourself look more important and/or more intelligent.
just a friendly heads up: it isn't working.
I have a line on 2 very gently used ones. Neither has been fired up in 10-20 years ! I just have to convince one of their owners to sell !!
