Great information, Glenn. I see they also have an "action" model specifically for sports - with an electronic stabilizer. If that one works well, it should take out the vibrations, worth testing. Besides 16:9, HD and good auto white balance that is a key requirement for onboards for me and the reason why I used a simple tape camcorder so far. So far very few compact race cams those features.
Do they have a standard camera mount/screw for a tripod etc.?
