This used to be my favorite mice, but it cannot compare with an overclocked mx510 with the "uberOptions" patched setpoint drivers.

Ah cool! I'd never heard of uberOptions before - but now I'm happily using it with my MX610 left-hander...and I'll stick it on my diNovo desktop later. Logitech rool ;-) W.

This used to be a favourite for gamers for one reason, and one reason only. It was the first of the high rez led mice that actually worked on most surfaces. as soon as they moved the same tech to the regular 'intelimouse optical (v1.1)' then people couldn't get away from the oversized explorer v3 fast enough, the way the base of the back stuck into your palm just by your wrist was terrible.

uberoptions setpoint? Where can I find these?

Oversized? How about its successor, intelliexplorer 4? Still the best shape through the years, if you ask me. I bought three of these and would have bought more if they didn't stop making them.
