although not would you'd call prolific, I've had very little trouble on ebay, mostly just a bit of hassle, only once did I feel I'd been cheated out of money, that was when I offered a part refund because the buyer said goods were not as described, and that was to save the bother of paying return postage, find out the buyer had done the damage and then having to resell, should have known he had very low feedback, lesson learned
