Gigabyte ECO600 Wireless Laser Mouse. While not entirely peripheral gaming device, it will work for this activity. I just thought I throw in here because it's really something special.
The design is sleek and curved lines, the first thing you notice (not to mention the color scheme of black two-tone), but battery performance that places the device above the rest.
mouse has two built-in button that allows users to increase or decrease the accuracy of the laser (800-1600 DPI in an increase 400 dpi) to conserve battery power. That means that small things will live for one year with regular use on a single battery.
This device is not yet available (indeed, it's just past by the FCC), but when it finally does not market, I suspect will also be an affordable option for more powerful mice that have been affected.
