Seeking 3-Axis Drone Gimbal

[Nintendoeats]

My brother and I would like to purchase a gimbal for my Dad. We are debating whether to get one that will support is GoPro and his phone, or his GoPro on a drone (Holy Stone HS700). Finding gimbals in the first category isn't too hard, but the second is starting to vex me.

It seems that you can be mounted to a drone, OR a stick, but I'm finding it difficult to positively identify that units:

1. Are 3-axis
   
2. Will work with his drone
3. Are good quality
4. Have a straight forward hand-held accessory (with more batteries would be nice)

Budget is in the few-hundred-dollars range.

Please help? Thanks!
