I'm pretty much sold on this rig for my 7D:
Redrock Micro - DSLR Field Cinema Bundle (http://store.redrockmicro.com/Catalog/DSLRShoulderMountedRigs/DSLRFieldCinemaBundleV2)

Just wanted to ask you guys opinion before I drop almost 2K on it. I'll be using the Z-Finder Pro 3x with it not an LCD.

Is there something less expensive that does the job just as well? Does it work as good as it looks?

Anyone have any experience with this one? It's close to the same price but no follow focus.
