Home/Hobbyist chiming in:
I have a German car up on a rotisserie in my garage so maybe we will be polar opposites

Are you going to be doing car-related stuff? What are you going to be welding? What gauge?
First thing you want to spend money on is PPE: Buy a GOOD helmet (WITH GRIND MODE), a good respirator, gloves, leathers, etc. Sorry, I know it's corny but you get what you pay for. We own two HF auto-darkening helmets (backups, loaners, etc.) but wife and I both have (expensive 3M brand) stuff --it's night and day... and worth every penny.
I have a bunch of welders (gmaw, fcaw, gtaw, etc.) One blue, three red and one (actually also blue) very old (made in Italy) HF/Chicago Electric fcaw.
Miller recently bought Hobart. Rumor is they wanted to sell blue wire like how red sells red wire. I believe that Miller is keeping the Hobart name and the blue boxes will be the higher end machines while the Hobart (white/orange/whatever) boxes will be focused much more at retail/homeowners/hobbyists. It's sort of like Lincoln Electric --if you see a red Weld-Pak 1xx with a NASCAR stocker on it, that welder was sold at HD/Lowes (some big-box retail store). If you find a red weld-pak box without nascar stickers on it, that person probably purchased it from a welding supply house (or direct from lincoln, or some other non-retail channel). They may have same "weld-pak 100" written on them but they are two different machines. (or they were... no idea what they are today)
If I could suggest one more thing (first is GET A GOOD HELMET!!): Look for a machine that doesn't just have numbers/letters on the knobs. It will help you a lot in the long run if you know/understand wire feed rate, amps, etc. ABCD/12345 doesn't do you any favors. You will be able to switch over much easier process-to-process (even fcaw to gmaw) if you understand that "letter B means n feet-per minute/second. Letter B tells you nothing. Understanding the numbers behind balancing amps (heat) and wire speed (glue/filler material) will advance your welding skills a lot. Even if you end up buying used, get something that has dials/buttons that translate back to actual meaningful numbers --not abcd or 12345.
Also, if you think you are going to fcaw sheet metal/body panels/thin stuff --it ain't gonna happen... Think of fcaw as baby stick (dirty, working out in field/remote, etc.) and think of gmaw as baby gtaw (clean, precision, control, etc.) fcaw and stick are more similar (flux inside vs. flux outside) whereas tig vs. mig there is the whole electrode/filler medium difference...
My Chicago Electric Easy Mig 100 is horrible. I wouldn't wish it on my worst enemy. I haven't given it away or sold it because it's so bad that I don't want to give it to anyone (in fear of them wanting to come back and murder me).
My red weld-pak 100 (with gas) is OK... ABCD/12345 settings. It's small, cheap, I can loan it out, etc.
My red weld-pak 140 is where things start to get decent. It's 240V, gas, aftermarket gun, etc. I teach people on that machine. Pretty much that's my normal go-to box. I still have the gas hookups on the weld-pak 100 but it's setup for fcaw as my "loaner". The red 240V weld-pak 140 is a really great little machine.
Then I have a red Precision 225 gtaw (and stick). That thing is awesome --but it wasn't cheap. Absolutely amazing machine. I probably can't even weld to 50% of it's capabilities. For my purposes --it's awesome and I love it.
I also have a blue MM 350P. It is also an amazing machine... Except I'm meh about it. I had a little blue MM 211... Then I upgraded to a blue MM 252?? (or whatever was just above the 211)... Eventually I landed an amazing deal on the blue 350P (long story but basically new/open box). I have 3-phase 208Y power at my home. gmaw with 3ph and a good machine is unbelievable. It's also night & day --welding aluminum with the 350P can be pretty close to gtaw. It's a VERY solid machine except I still find the little welding cart with the Lincoln 14o gmaw on it to be less hassle.
Look for real wire speed/amp numbers and don't be afraid of a 240V welder.
Hope that helps.
