I don't get this Amazon hate. Weren't they the ones who originally came up with the idea for putting purchaser reviews with the product, and the 5-star rating system? It seems like their solution was to 'crowdsource' the problem. Now people have learned to game the system, but I buy plenty of electronics from amazon and from ebay, and I'm careful enough that I've never ended up with a counterfeit.
Edit: I've noticed that ebay gives seller ratings, and amazon does product ratings. I guess that belies the different focus they each have. It would be cool (and probably a big improvement) if amazon put both product and seller ratings in equally prominent positions.
