Razer Diamondback (Razerzone.com is down(!)) Plasma Limited Edition for $70.
1600DPI, 5.8MP, 6400+ FPS capture, 16Bits, high motion dettection 40 inches per second
Also note:
“Razer was not only one of the first to be bold enough to release a 1600dpi mouse, but have taken it a step further with the plasma and have added the first ever infrared optical sensor for optics powered by Razer Precision.? Yes, that means it is invisible.? No more red glow emanating from the bottom of the mouse.? The bottom features some rather large Teflon feet for smooth tracking on any surface.”
