I am just kind of worried, $250 is a lot of money for me. On the other hand I don't want to worry about my system being damaged. I'm looking at getting the PW2RAUD or the PW15RAUD. Am I getting the best surge protection for the money? Thanks... james p.s. one concern I have about power in general is that I run my whole system from one outlet in a seperate room to my home theater by the way of an extension cord, it's the thick looking orange type of cord if that helps. Is this damaging to my system?
