I've been less than happy with my Go Pro Hero HD. The battery life is a joke and it malfunctions all the time. I'd go for a different brand. The video quality is pretty good it's just screwed me out of to many good laps on camera.

You aren't going to have 4 days to perfect it though.
Rodger, can I come? ha ha
