Crutchfield has the remote for $40:
Pioneer CD-SR80. A little pricey, but a very cool remote indeed. I may have to add one to my box -- I've always wanted wheel-mounted controls.
[Edit] Crutchfield also has some more expensive Blaupunkt steering wheel remotes (including some colorful Thummer 3s) and an ugly Kenwood remote. The Pioneer looks the best, in my opinion.
