Very briefly: Most people in the tech/arts field make their own devices for
different specific needs (I'm sure you can find most of what you need in a
RadioShack store or similar). If you need it fast, don't like soldiering
and have $650 to spare, try the GiraffeCam, supposed to be great.

ourselves is an old VCR attached to a helmet.. looks a bit funny and might
throw you off balance, but it works! :)
Good luck
