I bought one of these when it was the Dillon MkIII. While it was quick on sheet metal, it is akward to use being a push cutter. As a thick cutter I found it to be worthless. Much easier , quicker and cleaner with a standard torch set. However, it does shine as a gas welder. Mostly because of the pistol grip shape not because it welds any better. Less wrist fatigue. Do I regret buying it? welllllll, um yeah. Would I buy another one? No, I spend the money on a nice Victor Jr. with a full set of tips
