I have got a TBS frame and designed my own 3d printed brushless gimbal.
You can get the files for free and 3d print your own gimbal, check this video out:

I also sell the plastic parts if you do not have a 3D printer, $35 usd incl shipping, look at this video and video description for more info: http://www.youtube.com/watch?v=fnAEkdHy9K0
