I am changing my system and have this Monster Power 3600 surge protector for sale. It is brand new in box. I will provide the receipt for warranty purposes. It was bought at a GoodGuys store. New price is $500. I'm asking $425 or best offer. I don't have any feedback here, but if you look at my Ebay accoun, dblcltch, I have 65 positive feedbacks. Please email me with any questions. Thanks for your time.
