If you look on this page ( http://www.kensington.com/html/1420.html ), you'll find MouseinaBox® Optical USB/PS2, Model number: 72123. I have that Kensington mouse. It is cheap, but feels fine, and matches my AluBook VERY VERY well. Go ahead and walk into a store and hold one up to your PowerBook. It's probably about as close to the shiny finish as you can get.
