If you build a lot of DIY gear, you want a quick way to move your camera between rigs. I had come across the Sima Quickonnect awhile ago (and created an episode about it), but Amazon quickly sold out of them. When they were back in stock, the prices were no longer a great deal.
Well, take courage Frugal Filmmakers! The Sima Quickonnect is still in stock at Amazon and the price has returned to an all-time low of $8.59. Get three and you qualify for free shipping. I love these little connectors and they have a home in every one of my rigs. Very handy.
