Recently there was a comment on YouTube concerning the PVC Stabilizer Rig. This comment spoke of a modification using a universal quick plate system that didn't cost very much. That comment lead me to this post at Frugal Photog, which detailed the system and praised its use. I was so sold on the idea that I bought 6 of these and integrated them into all of my rigs. Now I can move my camera between rigs quickly and I save wear and tear on my mounting threads.
