I just Bought this

Yup. Intellimouse Optical or Explorer or Mozilla or whatever it's called here. V. Good except for the really annoying clogging-up of the glide strips. Still, easier to clean that ball-rollers...

I use an Intellimouse Optical too, have for two years already and I'm still absolutely in love with it. I like the fact that you can use those "extra" buttons in Windows without having any extra mouse software running. For the graphics work and web browsing I'm doing I wouldn't want it to be any heavier, it already feels as bulky as the ball-equipped MS Mouse 2.0, and a lot bulkier than most cheaper MS and Logitech mice. I bought my sister a Wheel Mouse Optical, and was kind of disappointed when it felt like a toy compared to the Intellimouse.

I am using Logitech Cordless Elite Duo wireless keyboard + mouse combo. Link here.

I am really satisfied with the mouse. It is pretty heavy, exactly how I like it. And the third button is IMHO in the only usable place. Now if only those regular left/right buttons were a bit bigger it would be a dream mouse. Like this, it took me a while to get used to, but now I wouldn't trade it for anything...

i use a logitech cordless optical....just seems to feel more natural in my hand than the microsoft ones, i think the logitech is narrower---i like that

the cheapest optical from logitech here (2 buttons + wheel, wchich is also a button...)...I can't even find it on their website...only something very familiar (with not so simple look). Exclusive oem product probably...but it's pretty good anyway...

p.s. so you're saying that ms drivers can be used with logitech mice? does it work only with ps/2? (I guess so...because on usb the driver 'knows' that it isn't ms mouse)
any advatages over standard windows driver for such simple mice?
