Helmet Cameras - what do you use?

denty85

I think i'm going to be doing the London to Brighton (british heart foundation ride) later in the year. I had a thought of maybe filming the journey. (i haven't worked out why yet, but i like gadgets!)

So on a budget, what cameras are out there to consider? I'm aware of the Oregon Scientific ATC 2k and 3k. are there any others you lot know about.

Cheers
