I have the 2G version of this model, also purchased from ebay for about 80bucks. It's a legit 2G capacity too. I first did a file transfer, and it stopped just short a few MB of 2G, I assume the other MB's were the file system or other hidden files that are necessary to keep the pod operating. I also took it a part and found the memory chip ID on this site. Samsung memory chip, also matching the memory ID as posted.
$80 u.s.d. + $16 u.s.d. shipping = $96 bucks
Thankfully, I was not burned on this buy.
