i have a samsung "40" lcd hdtv, xbox 360, blueray and comcast HD cable box, and soon to come a Onkyo HomeTheater system (model # HT-S5100, like tomorrow soon haha). Will that surge protecotr i have (using right now with the 1st three electronics) be capable of protecting total 4 electronic devices of this magnitude? i'm well aware of the 130-200 dollar Monster surge protector but if i don't have to spend, i won't. please help.
