maybe i need to do that, cos $450 is a lot better than 1k!!!!!
Its worth a try but if he isnt keen on the idea or you dont trust him just write it off, you dont want to lose $450 trying to save $550. Sometimes its cheaper to just pay the money.
Call him, see how it goes and use your gut instinct. Even with paypal security he can still fuck you if he wants by sending some old shit board or even just by taking months to get a refund out of him/paypal, Ive had that happen but always got my money in the end.
