You could also use modified RTI T2’s Like I do, I hate pronto's also. Everyone said the T2 was best remote for under $3000.00 but was very unreliable, So I now take them apart and make them reliable. I actually like the T2 better than the Crestron stuff. Its easier to use and program, further, It can do almost anything the big boys can do, RS232 and all.
For under $1000.00
