affordable gimbal

any one know of an affordable gimbal ?

for use with the black magic production camera or the cinema camera

What do you consider 'affordable'?
Cameras with that weight demand something quite sturdy, a cheap basic gimbal will not suffice, even if you can find really good ones for less than 1K U$, these are quite limited in what they can carry.

You can try the Zhiyun Crane 2.

The Zhiyun gimbals are good quality. But even then it depends on your whole configuration if the Crane 2 will be adequate (lens, external power, monitoring?).
