Picked myself up one of these the other week Veho Website - Product Detail £119 from Scan comes with a whole world of mounts etc plus a remote. It records in .MOV files but seeing as I want to be doing any editing in Windows Movie maker I had to convert it to a WMV file. Ok its no Gopro but its half the Gopro Motorsport price & with twice the accesories
I had one of the cheapo ones off ebay it was dreadfull the picture was wavey as hell and the sound was even worse, used it once then binned it. The quality is better before I convert the file, will find some editing software that is compatible with MOV files It does full 1080p 30fps but is better in 720 as you get 60fps. It will also take 5mp snap shots this can be done via the remote.
This one cost a quid! In all honesty I'd love a Go-Pro, but I just can't justify the cost. The camera in the first vid I posted plugs into the bike's power and will record continuously; you can take up to four hours' footage or just let it keep recording. The only minus point being the annoying date stamp in the corner of the screen. But for £15 I can live with that.
