i did the math and the cost of tanks, torch, filling the tanks your looking at the price of a cheep decent plasma cutter...add in the cost of refilling the tanks and by the 3rd time you fill the tanks youve bought a top of the line cutter capable of 1 1/2 inch deep cuts.....if all you doing is cutting that is
i was looking at 230$+ for each tank or a "rental" at like 50$ a month , about 100$ to fill each tank , and then buying the actualy hoses, guages, torch....i will admit i found a complete used setup more than once in the 300-500 range with tanks but at 200$+ to fill the tanks it spooked me into a plasma cutter
