For short races I use a cheap Sony Cybershot with a video option. It doesn't capture sound, but the wind noise screws up sounds with a Cobra anyways. These cameras are cheap on e-bay and produce video ready for the computer. Resolution is limted to 320x160 as I recall.

For long races I use a standard DV video camera and then bring it into the computer with firewire. This takes a more sophisticated setup, but you can do more tape.

One thing you _must_ buy for the Cobra is a protective lens. On the track, dirt will fly around and pit the lens. Better to pit a cheap protective lens/filter than your camera lens.
