Try the Logitec harmony 300. Best Buy has them for $30. I bought one for my Philips CD60, Marantz AV550 and reprogram it for other various mid-fi stuff. While it may not truely replace the OEM remote
I have yet to find a situation in which the basic functions didnt work. If you've never used the Harmony
remotes they are programed via your computer and an internet connection to Logitec. You then drill down to your specific machine/model. You can even reprogram any button to perform any function you like. It also controls four devices. For $30 its quite a remarkable remote.
