Dave,

I am in Oregon and all my stuff is from and in the US

Wow I am pretty confused. You definately know more about this stuff than anyone. I have a very simple set up and need some help. In my theatre (downstairs) I have a TSU2000 and an IR543 controling some lutron swithes. Everything works well but the remote has to point at the IR543 to work it (line of sight IR issue).

NOW, I just remodeled the kitchen and bought a TSU3000 and the RF extender. I want to control a stack of electronics in the living room since I can now hear them in the open floor plan and I want to conrol all the lights with X10 in the kitchen and the living room. I like the idea of RF so I don't have to point at the box to do it but I quess the RF extender will take care of that issue..

Am I missing anything?

Thanks for you help in advance...
Todd
