Logitech Steelseries Kinzu
Well, they look durable though I had mine for a couple of months only.
Funny how the only thing that bugs me about that mouse is it's lack of side buttons.
I think they go up to 3200 cpi, they are lightweight, not oversized. I love their lift off distance since they're optic (though laser mouses don't seem to have that issue no more). It's wire is nice too. I bought the white one (smooth top, easy to clean), and the black one is texturized and has a slightly better grip.
Seriously though, I think I understand your dislike for side buttons, but your experience (like mine) may have come from a poor design alied to not being used to it. My friend's razer had a real sensitive side button I'd press unadvertely every time.
Better designs don't have that problem though... And well, an extra button like that is really hand, picture Left 4 Dead for example. It doesn't use that many buttons (left fire, right push zombies back, middle zooms sniper while the wheel cycles weapons). The second time you switch weapons rather than zooming you'll be regretting not having that side button.
