I have a chinese gimbal branded as "goodluckbuy". It uses DYS motors and alexmos 32 bit controller. Cost me under $500 and works perfectly, BUT I had to unmount the whole thing and reassemble piece by piece. That's the price and I'm very happy with it. (using a 5d MK III with a Samyang 24mm. Next week i'll change it for a A7RII and a Sony 28mm)
