I had no idea MAPP was discontinued. I've never used or needed it, even on my rust belt Subaru ball joints. But I keep hearing people referring to MAPP for high heat, so what are they referring to if it's discontinued and not this?
It's a mix of MAPP and Propane (MAPP - Pro). Propane burns at a temperature a little below 2000 C, Mapp-Pro bumps it up a little (to like 2050). The old map was more like 2500 or higher if mixed with oxygen.

I've heard discussion that maybe Mapp-Pro is better than it sounds because of some heat-transfer quality, but I'm not qualified to speak about that. You can also mix oxygen with propane to increase it's temperature, so I suppose it all depends on what you're aiming to do.

I still use MAPP Pro occasionally, when I get a good price, but it also depends on whether you have a high-heat torch or a pencil flame.

For speed? Or for a particular application?

I have managed to stick with propane for now. But I haven’t had to solder anything bigger than 1/2”, and no massive brass fittings. I’ll admit that there was one pipe where I struggled because of a small leak dripping water into the heat zone. I’ve wondered about getting a MAPP torch… not sure if I’m being stubborn or restrained…

Maybe I'm fooling myself, but I feel like the yellow bottles get things hotter just a little bit faster. I understand the peak temperatures aren't terribly far apart, but Mapp Pro is still a bit higher. If I'm heating a rusted fastener, I don't have to do it as long.

It's not a dramatic difference, but I still pick up the gas when I get it for a decent price. If I'm paying $14+/bottle, I just make do with propane.

Busy Bee tools is having a clearance event. Discounts on clearance and a stacking 15% off code.

Looks like there are some deals to me - I didn't bother curating a list since it depends on what you're looking for. There are power tools, accessories, consumables, machines, etc.

Need a tiny arbor press? This would be like $34:

My order arrived. Regretfully, it is not a shop crane.

I did not even open the box. I could tell right away it was much too small to be correct. It says "Engine Support" on the box.

Wayfair's customer support leaves much to be desired... First I tried logging into my account and choosing "Problem with order". That askes a series of questions, but then dead-ends with a broken link to contact customer support.

Then I tried the live chat option - which obviously isn't "live" at all, it's just a chat bot. I went through all the same steps only to have it tell me I could keep the item and it would give me 20% off. Ah, no thanks. When I asked for a refund it said basically: "sorry, I can't do that".

I explained that purchase agreements don't work that way. A company cannot offer a product for sale, accept my money, deliver something different and then require me to accept it. Also, that sort of activity is defined as a "unfair practice" under Alberta's Consumer Protection Act, exposing the company to legal liability beyond a simple civil action.

That's probably unnecessary, but I was getting annoyed. At that point the bot gave me an option to communicated with Customer Service via text.

The first agent again offered me a 20% discount to keep the item, which I declined.

By then it was bedtime, but when I reprised the conversation in the morning I spoke to a new agent - who was actually surprisingly helpful and agreed to a refund and a FedEx pickup.

Assuming you get the wrong item too, perhaps this tale will help you skip to the part where you get to speak to customer service. I think you could probably just ask the bot for that and skip all the nonsense in-between.

Same here.

Delivered today, went straight to customer service and got 100% refund and free return pickup.
