shure they are not the best but they are dang handy when you want a CLEANER cut, my experiance with the oxy is always a ugly cut, bubbles warps all kinds of things, cutting wheel is definatly the best so far as long straight cuts but plasma can cut precise circles if you take the time to make a special tool that you bolt to the center of your circle there are small holes in it to put the tip of the plasma cutter in to make different sizes of circles, it just using it right.
what i need are prices and sources where to find them, not how much you dont use them... thanks
