I paid $120. My reasoning was that I knew one of my gimbal motors was bad, but I wasn't exactly sure which one. Each motor alone is between 30 - 40 plus shipping. So I figured for $120 I can pick up a used gimbal/camera and even if it is broken I hoped to salvage the motors from it. I got lucky, the one I got is perfect and works like new. So I ended up just replacing my shaky one which I may sell for parts (or keep for parts). When I installed another camera, I could not pair the controller no matter what I tried, I spent an hour trying. I thought the camera I got is bad. Then I realized that it could be on older firmware. So I loaded the SD card with latest firmware and let it do the upgrade, which it did. After that, it paired with no issues and works perfectly.
