Big Balance is a company that has been showing off a few gimbals over the last few years, but until now the products have not been available for purchase. While i'm not sure when these products will be 'officially' available, they continue to show off a few new additions at the recent 2014 PhotoPlus Expo.
If I would have to choose one i'm most interested in, it would be the Gibbon pistol grip style 2-Axis Gimbal for cameras like the GH4. With the newly developed dual handle addition, the Gibbon becomes a full 3-Axis stabilizer offering much more stability when walking or running. Many of the products shown in the video aren't yet available on the website, but there is additional information on other products over at the main website at https://bigbalance.com
