Charlie,
We need some alternatives to the video postings here to far. Please post some footage and information. I am looking for some equipment, but not being a videofile, I don't know what is out there and will work without lots of extras or add ons. Cost is one objective, but would like to know the full spectrum so to speak. There was good info from a search on camcorders. One thread was:
Inexpensive solid state in Car Video System
Let us know what you have, what works, and what you got at the track.
Bill
