Guys, listen...
The names Bernd Binder, Roland Geiger, Kralle, Tibor Toth and whatever else you have heard, they could all have been used by someone completely else. (BTW, I did a quick look and there are something like 10 different Kralles on ebay...)
Go check with your bank, if you sent money via money-transfer, to get the name of the recipient. Or pester Paypal to give you the account-number of the recipient and check that out. Bear in mind though that non-us Paypal accounts don't have verified addresses. At least mine isn't. Then maybe you'll find that the account is closed and whatever he is named has left with the money, or maybe not. Most low-lifes don't care if they leave their real name though, as they most likely have spent the cash before they get caught.
Just make sure you are chasing the right guy before calling in the cavalry.
Best of luck to you all, I hope the PPC cards turn up or you get your money back.
