In case you were looking for a Logitech Illuminated Ultrathin Keyboard with Backlighting

From TechBargains. Amazon: Price after rebate: $39.94

I just bought a used one from Amazon Marketplace for around the same price. Definitely a great keyboard. The top right button toggles the brightness of the backlighting through 4 steps (including off).
Be aware the modifier keys aren't quite right on a mac-- the Windows key is "command" and I haven't quite figured out if the one immediately to the left of the spacebar does anything.

you should be able to remap those keys.

You could remap the keys in System Preferences->Keyboard

Edit: Should have refreshed thread before posting, jdc beat me to it.

I have one of these. A great keyboard for the price. If I could only replace the Window's logo with an Apple one on the command key...

...the Amazon price on the keyboard dropped by $10. Call Amazon to get a credit for the price difference (thus you only pay $30 after rebate).
