i've thought about buying a good set of torches, as in the summer i tend to do alot of cutting (between working on projects, scrapping, and derby cars). after talking to my buddy (who generally fills the torch tanks) it seems that a plasma would be a much better investment. more expensive initially, but worth it in the long run. we're on our 5th fill on the bottles this year, and at $100 a pop, it wouldnt take long for the plasma to pay for itself. can anybody recomend a good trouble free unit, that would cut up to 3/8" steel, maybe even up to 1/2" occasionally, for a reasonable price?
