Just a quick warning against using paypal, about a month ago I sold an item, payment was recieved, and the item was sent to the buyer but I then was contacted by ebay saying the account had been comprimised and not to send the item etc. obviously this was too late and I told ebay who said to contact paypal which I did, with prove of sending, I received very little correspondence for a week or two, then got an email saying it had been resolved, so I assumed this meant I'd got my money back, oh no, they'd refunded the guy and didn't even tell me in the case closed area, I had to hunt around to find it.
Clearly Paypal and Ebay aren't there to look after the seller, luckily it was only for £35, but its the principle more than the money, and the fact that some scumbag probably has my item for free, plus there's loads of similar cases online for big money.
