I don't buy from overseas... period. Only int'l country I'd buy from is Canada... and that's only if it's a small amount of money. Just not worth the risk/time IMO. Particularly most Asian countries. If you know how retail works over there, the seller wants cash, and the buyer wants to phsyically inspect the item before handing over the cash. If I can't do business like that (which you can't w/ eBay), then I'm not doing business with them.
It's not really one particular country that's a problem. You just gotta understand how retail works over there. If you're from America, I can see how you wouldn't know.
