For 1000 an escrow service of some sort might be the best bet, but you shouldn't have any trouble with paypal. John
Moneybookers could be the first choice then E-gold i would say moneybookers because they dont have the chargeback option right in the transaction details but if some1 scammed you you could contact MB team and explain everything in this case they would refund the money so the buyer cant refund the money without clues
I'm sure that they're buying the site. If I were to use eGold, it wouldn't be for anything with such a value.
