Here's a suggestion for people considering filming their biking.
I recently bought this Sanyo Xacti C65 waterproof digital video camera.

It costs as little as
about £150.
It uses SD cards, so I fitted an 8gb card.
It can be hand held but has a standard tripod mount on the bottom, so I bought a
Ram camera mount for just over £20, and fitted it on my handlebars.
The battery life is actually the limiting factor. It will record on an 8gb card for far longer than the battery will last so I bought a spare battery and a
battery charger that runs off a cigar lighter locket, meaning you can charge one from the bike while using the other.
The battery was a tenner and the charger about £15.
So for about £200 you get everything you need to make The Longest Day video, which was done entirely using this kit.
I used the free video editing software on my Mac but Windows has something similar called Moviemaker.
