I bought a Lincoln 110v for around $350 delivered a couple years ago. Yo can get them on ebay for about the same
here I have had zero issue with it. I have built a frame with it using flux core and haven't had any welds break (lots of hard miles on shitty Nebraska roads. Lots of long trips fully loaded). I used it to build a trailer as well with zero issues. I know that people will talk smack on them and probably tell me my frame will crack and I will die and it will all be my fault for being cheap and stupid. But it's what I have and I use it all the time.
I have purchased 2 shitty HF welders the first one never worked and the second one did for about for about a 2" weld on low. I wouldn't buy one; but that's my experience.
