Buy.com has the Iogear GKM571R USB Wireless Mini Keyboard w/ Trackball for $50 with free shipping. Features a trackball equipped with a scroll wheel and LED backlighting.
I have one and it's a pretty decent HTPC keyboard. The trackball is a a bit more usable than the Logitech DiNovo's micro track pad and the scroll wheel is really handy. The downside is sucky battery life. It's a good idea to keep a spare set of rechargeable batteries because they don't last long.
