Adorama has it on b/o according to their site.
I've been using it for about five years and it's great for set-up and expedites lens changing. I have a similar quick release on the bottom of the gimbal and also on my ball head which also facilitates quick changes. Normally, speed means very little, but when I go from a big lens to a wide angle, or back, to accommodate my choice when time matters, it works well for me.
Venues in salt marshes or parks like YNP are good examples.
I found it was easier and cheaper to have two tripods , one for the gimbal and one for the ball head.
