FYi, a few weeks back I did an overview of the CAME 6000 2 Axis Active Stabilized Gimbal. My initial impressions were that the unit worked very well with my Panasonic GH3, but was awkward with only a single top handle. I immediately 'modded' my own side handles to the unit.
I guess they thought it was a good enough idea to now offer an upgraded version of this Gimbal with two new side handles. Great to see this company is fairly quick to respond to customer feedback. Unfortunately it does add a bit more to the original price, but unless you already had a set of handles, you'd probably end up spending the extra costs anyhow.
BTW, the rear door of the battery tray can also be removed if you want to add a larger RC battery. You can see the new version added to their website page (here)
