I would suggest a "Steddiepod" by Eddie Barber. I got to play with one at the Chicago Video expo and it had our AG-DVX100 on it...very nice. Its also a few other things like a monopod, boom, etc... CHeck it out. I dont have the website off hand, but a search on Google will get you plenty of information.
