I put together using the frame using an Interfit Studio Light Tent from B&H.
I cut down the frame still using the corner connecting parts and added
a cheeseplate, top hand grip as well as 4 corner grips. The "real" out of pocket cost is about $100 (no "free" parts laying around") which
includes $15 cheeseplate and $25 for hand grips. This is my 1st diy for my 7d and I am brand spanking new to HD video.
I still have some work to do, such as cut down bolts, add quick release and mounting options for monitor and audio.
