Have you already made your decision?
I would like to recommend a 3-axis gimbal for you ; it’s called MOZA from Gudsen. Maybe you didn't hear it before, but some of its features sound great and interesting. It has built-in wireless video transmitter, wireless remote controller which can not only control camera movements but also camera record and focus. Its wireless and tool-less design makes the overlook very clean.
If you're willing to spend and learn, the MOZA is the way to go without a doubt, it requires no tools to balance and little practice to use. The ability to have a thumb controller for the pan and tilt while operating is also a great benefit.
