Ebay can really run hot and cold. I bought SPC 2.0 and 2.5 II boards and they came through fine. I also got a pair of Audit locks w/keys successfully as well. However a couple of years ago I got set chips for an IGT S+ and they came through with bent pins. I think they were bent from poor packaging and getting crushed in the mail.
In reply to Shortrackskater, he's on the money. Ebay supports the customer quite well. As a seller, I had someone who (through Ebay) forced me to take a return and refund the money, even though what the guy was claiming (a prop used to show the item wasn't included) was explicitly spelled out both in the title of the ad and the body.
Definitely go back through Ebay or PayPal.
