I've been flying a Hangar 9 Ultrastick this summer. It's been a good plane, and I'd buy it again. I picked it up for $119 at the local shop this spring, which is pretty hard to beat. It sinks right in on landings without the flaps or crow settings. My only complaint is the stock tank. It burst on me in August. I'd read that I should have replaced it, but did I listen? Not until it bit me.
For a few bucks more than the SuperStick or older GP stick you can get an UltraStick that has better covering. That's worth it, I think.
