RTI T2+, but a dealer will have to program it
for you. Everybody who mentions it should mention
the fact that the software is only available to
dealers.

Perhaps their earlier models, for which you can
get the programs, will work -- I haven't investigated
them.

I came to RTI after programming lots of Prontoids
(Pronto and Marantz, NG and OG), then I programmed
a 5200 for myself and my wife around the time
our company switched to RTI. I couldn't stand
it. OMIGOD it is so much easier to use a remote
with actual buttons you can rest your finger on
while watching the TV, rather than having to look
at the touchscreen every time you do something!
