We took our new Came-7000 (for DSLR up to 6.6lbs weight load, total maximum weight of the gimbal with camera would be about 10.3lbs), outside for a spin, to test it's quality and sturdyness, and this thing is WAY better than the goodluckbuy.com or ebay's extremegadget product (same company), not to mention, WAY better customer service as well.
We have put together a full page of how to DIY on this link mdifilm.com/2013/?p=1291 hope it will help!
We can build this for you or have it available for rental with operator in Cleveland area.
An actual review will come later, for now, enjoy.
PS: CAME-7000 is the same as DYS or the Eagle Eye gimbal system.
