Gimbal for housed Gopro

[mpd79]

Having persuaded Santa to  give me a nice new Hero4 Silver, I am now to worried to fly  it without the case! It';s going on my 680Pro, which touch wood, is flying well (running3.2). My gimbal is overdue to be replaced, it';s brushless but taken Some mighty whacks in the past! So i wondered if anyone has a suitable suggestion for a case friendly gimbal?

I was thinking of something possibly servo based controlled by the pixhawk, with decent digital servos they seem ok. The budget, sadly, is very limited!
