OK let's start a thread on onboard videos. Cameras are cheap enough nowadays that you shoud at least have a few onboard to get all the different angles.
Here are some cameras you can look into
Lots of reviews here for the budget cams but some of them are as good or better than the name brand ones:

Some cameras which are good to use (wide angle) for forward view
Gopro3, Sony HDR AS10, SJ1000, mobius, contour roam
For those interested in a vendor in the US

I think I'm going to use 1 mobius cam with a wide angle lens for a fwd facing view, and 2 cheap er 808 cams for a rear and wheel angle view. Or you can even mount it remotely to check if something is rubbing or see how your driveshaft behaves under load.
