I have the Logitech MX-Revolution which is a very good mouse. For me though the flywheel is a bit sensitive which can be annoying sometimes (if you nudge the mouse while watching something it will pause it!). Range and tracking are excellent, and it's got plenty of buttons for faster browsing/exposé shortcuts etc.
It only comes in black and grey that I've seen, but this fits my scheme better since my MacPro and cinema display (second monitor) are silvery, while my HDTV (main monitor) is black/grey. Really my keyboard fits the least since it's the older all-white Apple wireless keyboard, I have one of the newer ones and while I love the feel I hate that it's basically a laptop keyboard so don't use it as I need a keypad, usable arrow keys, home, page-up/down keys etc., while obviously Apple thinks I should not =/
