Best Buy offers the Logitech G500s USB Wired Laser Gaming Mouse, model no. 910-003602, for $39.99 with free shipping. (Amazon charges the same.) That's the lowest total price we could find by $22, although we saw it for $2 less in January. It features 10 buttons, 8,200 dpi, in-game sensitivity switching, custom weight tuning, and a braided cable.
