same thing happened to me for a DireTV HD tivo a couple years ago. Sucks. Never got a cent back from Paypal. Scammer did the same thing to 20-30 people at the same time from my recollection. The price has got to be worth the risk to me. When you can buy a new one for $399, why bother with a used one on ebay?
