M-Audio Revolution 5.1-at newegg for under $80,is about the best buy for real quality. You always want to be aware of static charge issues. Much of the puters innards are sensitive to static electricity which your body can have a charge-you won't feel,but a soundcard,ram chip,or cpu will. Leave your machine plugged in (to a proper grounded outlet) and OFF-then just touching the bare metal of the case grounds you,discharges any static,and its safe then to handle the electronics.
