Beware of HF plasma cutters. The one I got died after a while. A few years. HF won't repair them or stock parts. Can't find a schematic for it either. It was not a good buy.
These kinds of equipment can be a crap shoot. We get enticed by the price, rather we get suckered in and buy, later to regret it. If you're willing to buy something twice, go cheap.
I'd like to get another PC, but I'm having second thoughts. If I had a task that needed it and justified it, I'd consider it. Just to have and crap out when you really needed it a few years later, not a good deal at all.
