What I like about my HP M547 is that it records unlimited(limited by your SD card) video. I mount it inside one of my shells to get onboard videos. Its a cheap camera($99 new, $40 used) that takes decent(read 6.2mp) pictures and acceptable video. Here is an onboard of my V-Twin. Also remember you are looking through the windshield of a Proline shell. All of my videos were shot with this camera.
