Best Mouse for Precision Gaming?

ubergamer asks: "Logitech's Dual Optical boasts two 800dpi sensors taking 2000 shots a second, Microsoft's Explorer 3.0 only has a single sensor at 400dpi but takes 6000 shots a second. Then there's ofcourse the Razer Boomslang 2000 with a single 2000dpi sensor but is partially mechanical (dust argh!) So which is best for playing my favorite FPS?"
