WarBeast Wireless PS3 Guitar
Sure, it's fun to play guitar on Rock Band or Guitar Hero, but it's hard to really rock with the standard guitars. The aptly-named WarBeast Wireless PS3 Guitar ($90) solves this problem with a wicked B.C. Rich design, and tons of extra features like an extended strum bar, dedicated "Star Power" button, a slide switch to choose which game you're playing, a removable face plate, and more.
