I decided against having one. My panel is a flat one by Aerotronics but I am using the Aerosport overhead and the center armrest. I have a quadrant, and I feel like enclosing it in a panel will just get in the way (besides, I like the industrial look of the quadrant). Not to mention it will make things more difficult if I need to get into the tunnel or work behind the panel. Just my $0.02 but I think we sometimes get too carried away in finishing off the interior.
