I've been using an Easom cage (www.easom.com) for a while now. Its been solid, has a great feel, easy to handle with plenty of room in and out. It adapts to changes in cameras/bodies/lenses without feeling too big. Excellent for HH work. Updating to add Lanpatre handles. Perfect fit for the Easom cage, great overall balance with the cage, cam, etc. I bought $5 of dense foam and shaped (use a band saw) it into a shoulder rest to complete the rig. Works great, Kevin
