I would do money order.

it is like a cheque you buy in post office
have him mailed it to you by snail mail. (the one with stamps :P)
wait for the money order to arrive.
cash it in. if it's a make money order, than you know its a scam
if you get the cash out. then don't send the item and sell it locally - PROFIT!.. LOL I am just kidding.
once you get the cash
send the item ..
slow but .. very safe
