This might be the biggest savings Amazon has had in their daily videogame deals yet. Of course, when you start with a $300 accessory product, you really need to make a discount deep to turn heads.
Today only, you can pick up one of these Mad Catz Fender Stratocastor replica guitar controllers for Xbox 360 at a staggering $99. They're wireless, wooden and sexy. I've not used one myself and am in no position today to spend a hundred smackers on a controller but I do wish I was. These look sick.
So, if you want to add a little bit more sophistication to your Rock Band or Guitar Hero game, perhaps now is the time. No telling when you'll get a deal this cheap again.

Overall, I would honestly just wait for RB3 and it's squire guitars where it's an actual full body guitar that you can actually add to the gameplay instead of being just another button controller.
Unless you're some sort of crazy rock band junkie like me :P
