I've wanted wanted of those since I've been on Geekhack!!!! Sell me one please!! I just don't whether I prefer the cue ball (would need to be an 9-ball for me) or the blingy lit up clear ball??
I'll trade you a Model M Mini for a modified trackball?? And I'll throw in 2 movie tickets and a toaster oven... ;-))
