I have been on eBay since 2005,1000 pos feedback,been ripped off less than 5 times when buying,never had a problem selling anything except the odd non payer.
There's paypal fees and eBay fees to come off your total so even if you sell for 2k you may only get 15-1600 in your hand.
Sure there's members on here looking for a 500 bumper.
