Thats pretty much the scoop I'm getting. I think the neighbor doesn't weld too much and maybe is just a little shy about it. But come to think of it, he was welding his frame when I was talking to him, not the body, but he did say he redid the window frame that way. Anyway, with my entry level skill, gas combo sounds the way to go! Whats more money for a gas cylinder anyway at this point, my engine money is dwiddling!
