Reading through all the posts on this thread.......my last comment.

Yes, the USS A-frame stands hinder your view of the audience somewhat (if you're sitting), but that's the price one pays for the protection it gives your keyboard. You could bump into that thing with an electric lawnmower and the whole frame will move but the keyboard will still be sitting on it's tier.

If you're playing for a dance crowd, no one is going to notice your stand anyway. Do a concert or a demo or any kind of an act under the spotlight and I WOULD definitely use one of the more "streamlined" stands.
