Regularly $50, the Logitech MX518 Optical Gaming Mouse is now on sale at Buy.com for just $19.99 after this $15 mail-in rebate (expires 9/8). This is the lowest price I've ever seen. I use this mouse (not for gaming but for everyday tasks) and love it. It is quick, precise and has eight programmable shortcut buttons. Shipping is free and there is no sales tax (except CA, MA, MD, TN).
