Please tell me you're not serious. I was actually thinking of buying one, just for the hell of it once I got a fightstick. If it's a hundred bucks for an ACCESSORY? Hahaha, sony/gamestop you so funny.
I just looked it up, granted only at two stores... both were selling it for below that price by a long way.
Although why you'd buy most of it brand new when theres tons of PS3 eye toys going cheap on ebay these days I don't know.
