Recently, I've seen threads about high-end equipment on ebay and people going back and forth about the quality of the seller and equipment. I've never bought anything off ebay for more than about $50. I'm weary of a lot of stuff on there. I prefer to buy from photography internet sites, but did buy my last lens at my camera shop because it was $10 cheaper there and no shipping.
