Razer -- Copperhead(red)

I bought a high-sensitive mouse from Buy.com. It's on sale at that time and I used Google Checkout to purchase this item about $47.99. The mouse possesses some cool characteristics like glittering red light and 4 extensionally customizing clicks. Software switcher provides programming not only 400~2000dpi but 125 ~1000 Hz of polling rate. A kind of big size, however, is uncomfortable. (maybe better after couple days)
