Hey, Chris… I have heard great things about all of the Hypertherm cutters! I think might be hamstrung by my air compressor if I go any bigger on my Cutter. I have the 60 gallon 2 stage Kobalt from Lowes. I believe that the CFM on this is near capacity? I absolutely could be wrong. But, I already bought it based on purchasing the HT 45. I knew there would be nickel and dime stuff along the way and in the end the HT45 was in my budget.
