I guess even if you sent the player back (at your own cost), he'll still end up sending you another player with hacked memory. And by the time you receive the replacement and find out it is hacked again, you'll probably get tired of all these sending back and replacement stuff and make do with the 512MB instead.

I'll file an ebay & paypal dispute over item received not as significantly described. But likely they will end up asking you return the item for refund of purchase price only. Either way, you would have paid for shipping to you, and shipping back to him.

You'll need to work out the sums on whether it is better to replace it (see above for likely scenerio), or pursuit an item dispute. With regards to the negative feedback that you might receive, i think it is possible to ask ebay to remove it. But you have to state the reasons for the removal, in this case he selling half the advertised capacity and giving you negative feedback.
