I'm getting tired of paying others to do frame mods for me, even though it is fun to hang out and shoot the bull while he is working on my frame, so I've decided to get my own torch. I was going to try MAPP gas but that is expensive for what it is and I think a torch might be a better investment. Anything I should look for? I'm probably going to get a used setup to save a few bucks. What recommendations do you guys have?
