It's a better deal for you since you don't have to pay Ebay their cut. I've done the same thing in the past. Even ended auctions early because someone made me an offer I couldn't refuse. BTW, once the money is in your PayPal account, he can't take it back. Even a money order is risk free on your part and you don't have to give PayPal a cut. Being the seller puts you in the driver seat. It's the buyer who's taking a risk trusting you. Go for it!
