Kurtz get a logitech mx300 or higher, its a good mouse and can be lefty
i paid 30 bucks for mine last week before i had the logi optical which is good but the mx optical is smoother and better built *ie ya pick it up and nothing rattles* i also have a mouseman cordless optical which sucks for computer gaming, cordless just skips to much for quick movements. s0 Kurtz get the logitech optical, or if ya want a free mouse i have some never used microsoft ball mouses for ya :- )
