Grip Unit adapter/relocator

[anatusa]

I its seems like a very useful tool for the rig:

i ve seen just these 2 units :

1. http://store.zacuto.com/Zgrip-Handle-with-C300-Grip-Relocator.html
in order to make it work on any rig u ll also need:
http://store.zacuto.com/Z-Mount-Zwivel.html
http://store.zacuto.com/4.5-inch-black-female-rod.html

not cheap i would say

2. Denz new Grip Unit Adapter
