Hi, I had a helmet cam , but due to the nature of snow boarding. It got alot of video of snow closeup's and trees. I found it best to have it on the inside of my arm and point.
But these look nice

Funny you should put up the Kodak playsport Steve as I'm narrowing in on one myself.
To get as close to the gopro without the outlay I reckon one of these at 720p 60fps with the addition of a fisheye or a wide angle lens mod (about £15 on top) I should be in business. Maybe not to the sport one actually, like the look of the Zi8 as it has a macro feature and a few bits and bobs that make up for the lack of an actual snow setting ... then again, the waterproofing may come in handy
