ANYTHING AND EVERYTHING on ebay is buyer beware. Read the full auction description and if the buyer doesn't back the item against being dead on arrival then don't buy it. 99 times out of 100 the item is still cheaper on Newegg, though.
Aside from that, our own FS/FT forums are much better than you'll find on ebay and you don't have to deal with the hassle of bidding.
