Here's my little review and test of this cheap gimbal from GoodLuckBuy
Aside from a few design issues, that may have been down to the fact I was using a GoPro 2 instead of a 3 (although it does state GoPro 1/2/3's can be used) I really like this gimbal. It's cheap, but it's managing to hold me picture very steady. For the price, it's really hard to fault it.
I'll follow up on this when I get some different landing gear, and have my GoPro live out coming out of the rear 30-pin connector. I may add a flight cam as well so I can tell what the attitude of the quad is
