Even without the eject hard key, there's always just clicking on the disk, and whacking E (command-E, for those of you viewing this outside of OSX).
If those Spacesaver models had been available a couple years ago, I'd not have picked up the Matias Tactile Mk.1 on eBay, though a hardware Dvorak keyboard may just tempt me away from this. Oh, by the way, this is a recommendation for the Matias Tactile if you can find one - mine is a Mk.1, but the Mk.3 is pretty nice, too.
The SMK-88 by DSI is discontinued, but it's pretty okay if you like linear switches (Cherry Black) and small footprints. The Happy Hacking Mac is quite nice - best membrane switches you will ever use, and rated to have about 3 times the service life of most membranes. Lots of reliance on function keys to get all the F-keys and the system hard keys, though, and it lacks the more modern media-playback stuff as well as dedicated Dashboard/Exposeé/Launchpad/Mission Control keys, but I've always just bound the right half of the F-keys since Tiger.
And that's just the stuff that's built for macs.
I know of no illuminated keyboards for Mac on the market, but I've yet to see that Razer ship.
