I've got the Monster AVL 300 and it sends both RF and IR signals, but the thing is, it doesn't matter. You put an RF to IR converter in your cabinet that has wires that spider out to all of your devices and attaches to the IR sensors on each device. The remote communicates with the converter via RF and then transmits to connected devices via IR thus converting them to radio frequency. For some reason, I found that all I had to do is put the converter in my cabinet and dont even have to run the wires to each device. It still converts all of them to RF. I've got the device inside a glass cabinet but it sends a strong enough IR signal that it also works with the devices that are outside the glass cabinet without running the IR wires to those devices. It's very cool and this remote was a great purchase. Programming it from the net can be a little tricky and time consuming. I had no problem setting up basic activities like "Watch TV" but I decided I wanted to turn on my receivers "zone 2" so that I could have the speakers in the other room come on as part of the activity "Listen to CD". I could not figure that one out by myself so I called Monster tech support and it was, by far, the best phone customer service experience I have ever had. The tech rep was extremely knowledgable and actually took control of the programming of my remote from her end and programmed the activity that was giving me trouble. For what it's worth, I also bought lighting controls and had no problem adding them to the remote functions or synching them to a couple of my activities.
I think the Harmony 890 is essentially the same remote and they may have great tech support, also. I just don't see how they can beat the Monster tech guys and, for me, that made all of the differance.
There are tons out there. Are there any that transmit in IR and RF? My satellite receiver is RF.
