Anyone got any recommendations for mice?

I currently use a Microsoft Wheel Mouse Optical which I got in 2002. It works fine but is getting a bit yellowed, so I am pondering getting a new mouse. I also lack spare PS/2 mice.

All I want, is a conventional mouse shape (non of these weird shapes), a left button, a right button, a wheel, and wheel (middle) button. Oh, and a wire.

Nothing more.

A lot of mice these days seem to either be funny shapes, have too many buttons or have strange coloured LEDs. Maybe if there is nothing new which is good I will just get an old stock Wheel Mouse Optical.
