The best method to protect buyer and seller that noone seems to have mentioned and is almost always done with contracts, is to send money in paper form (MO, Cashiers Check, Personal Check) but as buyer, withhold 20%. Seller receives 80%, money clears, ship game. Upon safe receipt of game, buyer inspects and if no gross flaws of misrepresentation are discovered sends remaining 20%. I do this with all my customers for contract work where I get X amount of money during various stages of completion of work with the final 20% awarded upon mutual agreement that the contract is completed. Granted, it doesn't fully protect buyer or seller, and there's still risk, but it does minimize the risk and encourages both parties to act honestly and above board prior and during the transaction.

Same here in reverse....I usually abhor paypal so I just send parts and have buyers return a check to the return address when parts are received. Haven't been burned yet.
