crank adjustable platforms

[paranday]

Of the current production crank adjustable platforms, which models are the best, in terms of no vibration? I know someone who just insists on wanting a crank model, hate to see him get a bum steer. If I recall, some of these vibrate like crazy.

I've only seen a couple of crank styles here (USA) and they are normally on pretty heavy duty boards, and vibration isn't as much of a problem as a sturdy wall to hang them on.
