Chinese 4 in 1
a reader from Europe here. I bought a 200A AC/DC Pulse TIG/stick welder with plasma cutter for about 800€-bucks half a year ago. I am not a very experienced welder, took a 75 hour class end of last year, but from what I can tell I can see no huge difference in the welds between this piece of "Chinese junk" and the obscenely expensive professional welders I used in class (e.g. EWM Triton, Rehm and a few others), at least when welding plain steel and stainless. Aluminum works fine, too, although the professional, Euro-made AC welders had a few more options (pulse frequencies, waveform, watercooled torch, differences in torch buttons) than my Chinese welder. But it definitely works great, for about 20% of the price. So far no complaints.
I haven't tried out the plasma cutter feature yet since I don't have a big enough air compressor at home, will try it out soon though.
Spare parts are available online from many sources for cheap, they seem to be interchangeable with many other brands.
The welder is being sold with 5 years warranty, and since I don't use it very often I hope it will last a long time. The seller has a pretty good reputation among hobbyists over here, no complaints about their service yet from others (still hope I won't need the warranty). If I ever need to have it repaird, no big deal for me, I can do without it for 2 weeks, I don't earn my money with it.
This is the one I have, I'm sure it's available in the US under some different brand name, too:
