Rock Band or Rock Band 2. Why would anyone want to pay 3/4 of a PS3 for a controller? Admittedly, it is a quality product with much attention paid to the details -- the pads are "ultra-quiet velocity sensitive pads" that are tougher. It comes with two cymbals, but the third one is sold separately. You can also position the snare, tom and cymbal pads in any way you want. The drum pedal is all metal and with the option of adding a second pedal. The best part is, you "can swap the game controller module with one of the professional drum brains made by Alesis" and you can use this as an actual electronic drum kit.
Considering real drum sets cost at least $500 at the bargain level, this is a nice accessory for those trying to transition from gamer to musician. Otherwise, you are better off sticking with the normal version. Check out all the details and pictures over at the official website.
