I didn't expect that much attention. To answer a couple of the questions: On price I saw it as low as $79 USD depending on which version you get. All have the back lighting. The LCD display can be set up for a wide variety of function, everything from a clock/date to RSS links that are scrollable, to monitoring your system, to monitoring in-game stats. Pretty slick. I like Michael don't look at the keyboard when I'm typing either but with less typos. 
I do however look at it when gaming. Yeah i have noticed the issues with too many functions being used when on the server. So far I haven't gotten too crazy. I can program 3 different functions per game key but only one is there at at time depending on which of the M keys is selected. I have set the M keys up so each is a different game which works for me since there are only three I play. I also like it feature that if I were to hit as many as five different keys/functions most keyboard would only take the first three, this one takes all five in the order entered. There is also a lockout so when I am in game, the Windows keys and the word editor keys are disabled so that if you accidentally hit one you don't end up out of the game and at the desktop. Also right above the numeric pad there is another mute key and a thumb wheel that controls the audio level. So there are two mute keys for the mic/earphones (1ea) and the master above the numeric pad.
Newegg, Amazon, Logitech, and several other sites have them. Logitech's site has one of the versions for $99 USD, Newegg has one for $79 USD.
