Hey guys I need a surge protector preferably with at least 8 inputs. What kind of surge protector will do, do they have to be made for home theater, or will a normal computer one do? What about the joule rating I noticed some protectors have a higher amount of joules. What does this mean, is it important. Oh and I want it to be as cheap as possible and hopefully available at a place like Best Buy, CC, Office Max etc but I will order one if I have too.
