This may seem like a silly question - but are all CUT 50 Pilot Arc machines the same? In other words - is it a type of machine - or actually a model from a specific manufacturer? I'm seeing them on Ebay for £180 - £190 at the moment, which as Christmas is coming, is just about within my reach. I know several of you have bought these from Ebay - there appear to be two suppliers at my price point - SUSEMSELOCK or MOSFET16 - do you have any positive or negative experience of suppliers please? (Happy to have it via PM if you'd prefer not to share that publicly). If I'm going to splash the cash, I'd rather have someone that responds if problems should arise Thanks.
