Its a Cineroid. But the exact same arm gets branded for other companys also. It was pretty cheap, you get the exact same one from Ikan for example. The quality is really good and it locks down tight.

Since its arrival, I have been perplexed by the accompanying soft case. It seems that the EVF has to be disassembled in order for part of it to fit within the case, the remainder goes where?
A call to Zacuto in search of a carry case for the entire unit proved fruitless. However, a search through my equipment closet revealed an unoccupied Cannon telephoto lens case (200mm)—problem solved. The entire assembled EVF fits inside with room to spare. And a small piece of cut foam placed beneath the EVF allows the charger to sit inside the case beneath the EVF. When I have a moment I will take a photo and post it.

To add to Brian's post Jon Fauer's site Film & Digital Times has a short piece on said EVF...

I have used both the Zacuto EVF and the TVLogic. The quality of the Zacuto's screen does not seem very good whereas the TVLogic is amazing. Without peaking, neither is good enough for very accurate focusing, mainly due to their small size. When using the TVLogic, I found it easy enough to get accurate focus. However, for shoulder mount shooting, the Zacuto was better when I didn't have to walk and pull focus while the TVLogic was a little easier to walk around and pull focus (using a Zacuto FF). I used a Zacuto articulating arm to attach them, which I also have used with a PIX240.
