I thought it was a wind up when I saw that helmet rig, quite a good way to sell your gear someone comes along now and asks how much you want for the Hero 3 quality did look good on the Sony though they did like the Gopro.
I bought one a few weeks ago. I haven't had chance to use it properly but for the price I'm quite impressed with early results. I also bought a helmet mount for it and, using cable ties, I've been able to attach it to a rucksac shoulder strap. Can't wait to get on the hill with it.
