The drift innovation hd170 is very similar to the other high end helmet cams on the market right now, 1080p video, very durable, right around $300. But there are two major things that lead me to think this might be a big hit come this winter. A built on lcd screen to view your shots, and a wrist strap remote to start/stop your recording. Priced at $330 US(includes mounts), I think this is a very good option. Only weighs 6 grams more then the gopro also. Here are some pictures(borrowed from engadget)
