As stated by all, save up and buy quality, you won't regret it. I personally love gas and I can do endless things with it. I also have a cheapola HF stick welder and a very nice Lincoln MIG. Each has it's place for different things, but if I had to choose just one for auto sheet metal repair, it would be the MIG, with the inert gas kit. But my Sears oxy/acetylene rig has been a trusted friend for 30 years and I could not get along without it, so I would say get one of those too. Hell, even the HF POS is handy to repair chain link fences and other grunt work I don't want to waste the MIG on. By the way, my HF unit was made in Italy and wouldn't work at first. I opened it up and found an important wire had not been secured, some kind of shabby quality control. The Lincoln was top shelf, right out of the box.
