video camera shopping

This summer I will be shooting lots of helmet cam video, as well as experimenting with different and unique ways to capture the spirit of park riding on film. My old camera just isn't up to the task. I will be posting frequent video on this site so I want the video segments to be higher quality for everyone's enjoyment.
