Yeah, I ran into the same thing a month ago selling kites on iKitesurf. A potential buyer, purportedly from England, wanted to send by his "agent" to pick up a kite and deliver a cashier's check. I asked if the buyer (whose email address was a Yahoo account, of course) if had a paypal account, of course he said no.

I told this buyer to kiss my ass--if someone has the time and clout to send his agent over, the agent can stop at an ATM.

Cash or true cash equivalent, screw everything else. The scammers are all over kites on eBay and ikitesurf so be suspicious of anything unusual when selling a kite to someone you don't know. All those jackasses have led me to conclude that's it's better to simply sell gear to your friends at a steep discount so you don't have to deal with the bullshit.
