I've got a SteadyPod, picked up cheap at NAB, works OK as a monopod also but to be honest I only bought it because it seemed the most goof proof of the lot.
I liked the look of the FlowPod until I saw it in the flesh, they need to do more work on how you balance the thing, I guess it'd be fine if you always use it with the same camera or else you could replace the stage with one from Manfrotto that has lead scews.
