Post up an offer of $158.63 but tell him you'll send a cashier's check for $1000 and you'll need him to send you back the change after he cashes it. Hand write the cashier's check from Bank of Nigeria. Don't send him actual check, but a camera phone picture of it. Tell him that his bank will accept it.
See how long you can drag it out with ridiculous stuff. Then see if he'll take your $140 offer. Then tell him you've had second thoughts, and you'll get back to him. Then don't.
