Hi, anyone had any dealings with ebayer racquetattack before? http://myworld.ebay.ca/racquetattack/ All his racquets seem to be priced so much lower, especially blackknights. the shoes and everything else seem to be on par with normal pricing. Also the guy has 100% positive feedback. So I really don't know what to think... would like to get a blackknight racquet off him. Advices please.
