I want to replace all 4 remotes with one unit that can easily control all my units. I would really like a Pronto but don't have a pc at home to program the unit. I now have a Sony touch-screen unit rm-2000? that just doesn't cut it. Its just too big for me, and It doesn't do exactly what I want. Can someone recommend a unit similar to a pronto or is that the way to go? If so Is it difficult to program it too control a dvd-rp56, avr-3802 and a old Hitachi tv and vcr.
