Beta does, but it depends on your handle type if it fits or not. They use thin metal t-handles like Facom and USAG. So its very compact. I'd be interested to hear on ones designed for soft/comfort grips.
Maybe some company could make one like this that holds the shaft, and the handles crossways like the motion pro. I think the issue is the handles are 1 in thick or so, so depending on your set size it might be kinda long/cantilevered and be unstable.
