www.dogcamsport.co.uk & have a hunt around on their site.
I'm thinking of getting either their 420 or 480 bullet camera. This comes with all the needed gubbins. They do a kit with a mobibox recorder (also doubles as an FM radio & MP3 player). 512Mb storage built in, and takes up to 4GB SD cards. Powered by Li-Ion battery & camera powered by 8xAA pack (supplied). Sucker mount (for helmet or bike use) and static mount supplied.
Cost? Approx £190 for the 420 kit.
