I'm interested in a helmet also. Track time at each Rally I've attended I've used track helmet. Time to buy my own.
The battery on my old one is not holding a charge so yesterday afternoon after the drive and before the meet and greet I went searching for one....
Frys does not carry any GoPro equipment. I asked the guy what GP did to p*** them off but he didn't know why they don't carry it.
The Walmart at Eastern and Russell had some accessories (I think they had the suction cup mount).
There are a couple of best buys around that seem to be the best places.
The GoPro web site lists some independents, two are in the outlet malls at LV Blvd and Warm Springs.
I haven't found a battery for the old gen, it looks like a Gen4 camera is the solution
