$399… Quite a bit :/
It’s just a metal acting as counter-weight.
I made something by hand, i will take a picture of it and post it here soon
I’ve never liked that arm that rests on your stomach or rig. I have a “custom” one made from a friend of my Dad who does some welding.
The rig itself is pretty heavy (8lb), but I prefer the weight to give it that over-the-shoulder broadcast camera feel, and it helps stabilizing it.
Theres always the spiderbrace.com one for even cheaper-cheapos
