I think the GoPro, video quality and mount-wise, is unparalleled. I've had it 100ft. deep in the Florida Keys, suctioned to my tank, and now I use a RAM mount for it on the handlebars. I have the original, not the Hero 2, so, no external mike, and I'm not fond of its aerodynamics hanging off my helmet... so it stays on the handlebar.
However, I just got in the Drift HD, as well. External mike, aerodynamic, rotating lens, remote control (wraps around your wrist), LCD based menu. However, the vid quality is a bit short of the GoPro Hero.
