110v China Plasma cutter

Have any of you had any success using these 110v plasma cutters in a cnc application? I see them popping up everywhere cheap I've seen a few you tube vids of one on a torchmate seems to work well. I can get one from a local dealer for $350 Such as this one that looks identical to this one on Ebay.
