Had this problem before. If you send something expensive, film yourself putting it in the box, write the serial numbers down, send it recorded or signed for delivery always, withdraw EVERYTHING from your paypal account instantly into your bank account.
A friend of mine however ended up with a debt collection agency (Transcom) after him for 6 months because he refused to refund the item. Eventually after much letter writing with "fuck off" in it basically, they gave up because there wasn't a genuine claim that would stand up in court.
I still buy and sell off ebay but it's usually very niche items which are on 1:1 interest and low value (vintage transistors for example). Anything popular, I get the other half to stick it on Facebook and it's gone, in cash usually within 72 hours. No fees, nothing.
