Looking to buy a plasma cutter. Need help on what brand and what model. I'll be doing anything from sheet metal to cutting my 40's bumper and maybe thicker. Needs to be portable, 110 & 220 volts dont matter. Price maybe an issue. I know I can pay 3 thousand for a nice one but that is to high for me. Try to keep it in the 1 thousand dollar area. Less would be even better. I checked e-bay and I got confussed with all the modles and brands. They all sound like the perfect one. Can anyone help?
