I'm using a basic Sony miniDV camera (DCR-HC38) with a 0.6X wide angle lens, on an I/O Port roll cage mount. I don't have a cage, so I kind of ghetto mounted it to a piece of 1.5" ABS pipe, and strapped that to the firewall where the CD tray console thing normally mounts to. It was good enough for now. And yep, NASA norCal allows passengers in group 2, although we run in the same group as the group 1 guys.
