I recently purchased a camera strap on eBay from a shop called thecamerahunter.
I never recieved the strap and my repeated attempts to contact the seller were ignored.
I allowed him too much of a chance to redeem himself and I missed both chances I had to file dispute (on eBay and Paypal).
As an avid eBayer who often purchases items on eBay I was surprised as the seller has a good history... but that doesn't change the fact that he has ignored half a dozen messages and eMails.
His shop is here. I suggest you keep away.
