I got a Lincoln powermig 255 a few years ago from linde gas for like 1500 otd. I can weld what ever I need to and still does sheetmetal very well. I wish I would of bought a multi process machine that I could do tig with also but at the time I didn't have the cash. From my experience buy bigger to begin with then when you need its there and you don't have to go buy a bigger one later.
Learn on scrap metal for frame work, never a vehicle to start with because its not only for your safety but everyones on the road. I have seen people learn on their own trucks and have had stuff break and luckily they didn't kill themselves.
You can always tack stuff up then take it to a professional to have them weld it up good. Costs a little but better then being broke down in the middle of nowhere.
Learning to shave stuff on your truck isn't a good Idea if your not careful and warp the hell out of a doorskin or somethin.
