If you use 12mm (1/2") wood for your CP, you can mount the Sparkfun trackball like Degenatrons shows in this thread.

You can get an AVR to solder your own here, here, or here for under $15 plus shipping.

This is the lowest price trackball/mount/encoder combination that I have seen.

The video and previously linked thread are pretty straight forward on how to wire the trackball.

The other AVR inputs can be assigned as HID buttons using the free KADE Loader software.

What other questions do you have?

My TI Launchpad based encoder will do 30 digital inputs plus a trackball or two spinners, and the Launchpad is all of about $15 shipped from TI.  No fancy interface yet like the KADE software, and the current firmware has it presenting as two gamepads and a mouse rather than a keyboard/mouse.  Shoot me a PM if you would like more info.  I've also done a custom 8 button keyboard/mouse version for another forum member which might work well for your needs too.
