Thanks for all the replies!
And @ Islandtees, I'm guessing the answer to your question is no. Or at least no one that does screens in their Ozzy setup has seen this thread yet.
But based on Rich's enthusiasm (also Brad's early positive review on another thread) I'm going to head that direction too, eventually. I just haven't needed such a thing, with my manual setup. Autos are a little different. All part of the learning curve, I guess.
