When is it available though? the Defy Gimbal is another option too. Their G2 model ships at the end of July. Both seem comparable, but www.defygimbal.com is worth a look.
I'm aware of the Defy Gimbal... it looks great and the price is much more appealing to the indie end of the industry. I'd love to get hold of one for review.. doing a piece for Digital Film Maker Mag and this blog on Camera movement and stabilisation soon.
