That Plasma cutter he is selling in his other auctions for $119 sells for $1400 new on Amazon and $950 on Ebay, so that is a scam, all of his auctions are scams. The way these scams work is someone gained access to that users password and took over their account probably with a fake email, changed the Pay-Pal address to another made up one he uses, then collects all the money he can in a short time period, then withdraws it and then disappears.
All of his auctions were just listed today, he has never sold anything on Ebay, I bet they willl all be canceled soon too. He is up to over $3200 on just the lathe auction already.
It will take close to a month to get your money back as you have to wait 10 days until you can turn a dispute to a claim with Pay-Pal, then they will have to investigate it for another 10 days.
If you bought one and have a completed transaction with that seller, request his user info and you can call him with the phone number he has listed with them, I bet it will be disconnected or fake though.
Here is the link you can request his user information, let us know what he says
