Steadicam has a smoothee, Cinevate once showed something for an iPhone about a year ago, Lensse has an iPhone version as well, but can be adapted to the GoPro. Somehow every company is finding a way to market tiny stabilizers for iPhones, Flip Cameras, and all types of point and shoots.
Olivia gets a demo from Tom McKay - President of Varizoom showing a regular FlowPod, as well as their new lightweight version. Now in the end of the video he throws out pricing, but when I was at NAB, I want to say that the smaller version was only around $150 dollars. That means it would be a bit cheaper than Steadicam's Smoothee as well as being a lot more functional.
I'll have to contact Varizoom to find out if the pricing he mentions was for the larger version that supports the GH2, because anything over $150 bucks seems a bit pricey. BTW, if you've followed Olivia's Vimeo profile she finally has her cast (broken wrist) taken off. Hilarious stuff... This was also a highlight from Episode 4 from her Myx-Rated Television show which is shot almost completely on Canon DSLR's.
