I like the Adesso ARC-1100 MCE Infrared Remote Control. Its designed for Windwos Media Center, but will work with JRiver. Just plug it in and it works (for Vista/Win7); no programming or software installation required (Windows automatically installs the drivers). There is third party software that would let you reconfigure the buttons if needed (for example making the Start button launch JRiver instead of WMC). It has a mouse pad too which most do not; comes in handy when things go wrong.
