I vote for Logitech Illuminated Keyboard, it looks nice, has backlight, feels nice to type on. Also can be bought for very cheap on refurbished models. Full price might be a bit expensive (running into mechanical keyboard price range) but shouldn't be too hard to find deals on this 
After using cherry mx brown switches for a month I switched back to my Logitech Illuminated. Although the feel and sound when typing a document was amazing, the feel when playing games just felt awkward (I kept hitting key cap edges, although keep in mind I have poor refined motor control). I felt like I was typing so quickly with the mechanical but when I actually recorded my typing speed and accuracy I performed better with the Logitech Illuminated. I stacked nickels on both keyboards and the force required was approximately equal between the two, not to mention the Logitech has shorter key travel.
The rollover issue has never affected me when typing, nor when playing games. I didn't even realize there was an issue until I read about it; W+Shift+Space does not work (I think I didn't notice this before as I generally rebind sprint) but W+Shift+Letter Key of any type seems to work fine. You can also hold W&A/etc and press two others keys... if I was doing any more then that I'd just be rolling my face across the keyboard.
I used a Saitek Eclipse at home for several years, yet the moment I used an Apple Aluminum Keyboard my typing speed and accuracy went up dramatically... so my clumsy fingers seem to function better with low profile keys (I type using mostly my index fingers and type 90-100wpm).
I would buy a low-profile mechanical in an instant if a decent one was available.
