I bought an Avenger A2030D C-Stand kit a couple weeks ago.
Anyway, I did a short write-up on it: http://www.ocabj.net/?p=1245
The C-Stand is definitely one handy piece of grip equipment. I wish I bought one sooner.
Unfortunately, I neglected to take photos of how I deployed it at a couple shoots this past month. But I did cut a video demo of it, and I have one short photo shoot video with a model that came down to SoCal from Reno where I used it and you can see it in a couple frames of video.
Anyway, check out the write-up if you feel so inclined.
Short behind the scenes footage of photo shoot:
Couple of visuals for those that don't know what a C-Stand is.
