I own an MX600, and I must say it's my favorite mouse I've ever owned.  A must have for any logitech owner, is the UberOptions mod for the Setpoint drivers.  (Google it, I'm too lazy to)

It basically lets you do program specific keybinds, so that even all those extra keys will work in any game.  I have my buttons bound as Q, W, E, A, S, D, F, and G for UT2004.
