He got back to me 


Any eBay sale I create I state at the bottom of the advert "feedback will be left upon receipt of feedback from the buyer" so if they don't give me any, they don't get any either. Works for me.
Paypal have 3 choices of account - Personal, Premium or Business.
They are all free to upgrade and the difference is that if you choose premium or Business account, there is no limit on how much you can sell on ebay.
Also, if you have a pay pal account you can demand payment as soon as they have added it to their basket.
Ive had a few businesses on here, and it's so much better knowing that the customer has to pay straight away.
