I have a RS15-2117, which supports the JP1 programming language (allows you to program it using a serial cable, add support for stuff that the remote normally doesn't support). I paid $30, came with an IR->RF repeater system as well. Not sure if you can find them at RS, since they have been discontinued. If you have Z-wave, you might want to consider the new Harmony remotes (or even if you don't have Z-wave, still take a look at them, they are pretty nice!)
