Not sure of my model number but I have the model with the LCD screen that is directly below the first color model. Dell has great sales on these remotes (and the higher models) every few months. Keep an eye on dealtime.com and they will let you know when there is a great sale on them. If I remember correctly I got mine for about $60 shipped and it does everything I need. Controls TV, Cable Box, DVD, Audio Receiver, DVR, xbox, and CD player. Just had to hook it up to the PC to download the profile and everything worked almost perfectly. I only had to change the function of a few buttons that changed the color modes and display resolutions of my TV. Another thing that amazed me is that even with the black light the original batteries have lasted over 9 months now without being changed.
I also really love the activity based viewing modes so that when you select watch DVD it will turn the TV, Stereo, and DVD player on. Then if you select listen to CD it will turn everything else off and just leave the receiver, dvd playe, and equalizerr on. Some people reported that the remote does not keep track of the on/off states of your components. However, in my case the only time I have seen this is when I turn the component off and on by hand and not use the remote.
It was well worth the $60 to get 8-9 remotes out of my living room (and not to hear the ridicule from the girlfriend while they were all there.)
