I'll second the RS 15-1994. I had a Pronto and actually got rid of it. Why? B/c there is no tactile feedback on a touchscreen. While I got used to it after a while, I would often find myself looking down and waiting a sec for the blacklight so I could fast forward or reverse my DVDs and TiVo, switch between modes, etc.
You can make a cable that plugs into the back of it so you can program with your computer (which is really pretty easy and very powerful.)
Beware, however, that the newer revision takes away some of the important hidden features, so I'd avoid it unless you just need a basic programmable/learning remote.
