I remember seeing a pair on eBay which i fell in love with, and wanted so bad. But they were up for pre order, and have since disappeared, so i am not sure if they were a con, or a litmus test for business, but they were still amazing. Proper stone , and the design was sensational. They weren't cheap, i think they were going for about $500, but god knows what happened. I think also, the person selling them was trying to set up a Shenmue shop of some kind, but again, i don't think it materialised.
