Cool. But, that thing is just too bulky. That'll give ya a stiff neck. lol Should be able make a much smaller rig.
I didn't buy my set commercially, just built it up from parts I put together from an electronics store. Costs me less than $150 for everything, not including camcorder that accepts video inptuts (which I already had).
I have a helmet camera for dirt biking or riding on a track or mountain/canyon roads on my street bikes. The helmet cam is tiny and just weighs a couple oz. Plugs into a mini digital camcorder, thats in a camel back or tank bag of sorts.
Here is basically what I put together from scratch (commercial version):
