newegg offers the GIGABYTE GM-M6800 5+1 Button Dual Lens USB Optical Gaming Mouse in Black for $9.99 with free shipping. That's tied with last month's mention and the lowest total price we could find now by $5. It features adjustable 800/1600 dpi resolution (via the sixth button) dual lens technology which purports to achieve higher precision, and teflon foot pads.
