even just the fact that the person singing his praises has only made one post here should be enough! not only is he a crook, he's a pretty stupid one. You'd think there'd have to be at least a couple of posts if only to begin the transaction, tell him what parts you need?
It's also the case that a lot of cons start out by ACTUALLY DELIVERING a few parts so that then they get a lot of orders, and money and then they disappear. It's called the long firm, or long con (some people used to set up businesses, selling fridges and other electrical goods, establish a good line of credit, then order a few truckloads and then the company and the goods would disappear, goods sold on the black market and debts never paid)
