If you did do it, I wouldn't accept paypal for payment. I'm too worried about how easily they take money back to use it for large amounts. When I sold some expensive stuff at Xmas, I stipulated bank transfer only. No problems at all, and you know once you've got the money in your bank it's really yours! I also explained to buyers that they could pay the money into my account over the counter at the bank (some buyers didn't have bank accounts they could do transfers from). I bank with HSBC, so they're fairly accessible for most buyers.
