Looking into adding a remote control pan/tilt unit to use in conjunction with a tripod or on the end of a camera crane. The camcorders could be as light as a consumer Sony HDR-HC1 (almost 2 pounds) and perhaps a little heavier than a HDR-FX1 (about 5 pounds). If I add a mic and high capacity battery, the weights go us about a pound.
I found the Bescor MP101 unit for about $125 and the Jony and others for $1,400 and up (Sachter, Cambo, Vinten, Barber Tech and several others). The Bescor can easily deal with the HC1; but is right on the edge with the weight of the FX1. I can't find anything in the $500-$1,000 range on which I would be comfortable with putting my FX1 (or other prosumer or pro camcorder of similar weight).
