Here's my zenith set w/ some smoke panels installed, inspired by the rca 2000 design.
The RCA 2000 was too big and bulky for me to ever get. I'm very happy with this setup, it's a remote set. No need to twiddle for knobs and panel does not interfere w/ remote operation.
Picture is somewhat subdued, yet better detailed at the sme time as panel eliminates light reflections from the room. Picture blurred due to timed shutter.
