Recently, I've been looking into a new surge suppressor for my system. It's been a long time and i'm looking to replace my old Panamax 6 with something alittle bigger though I like the Panamax name. The build quality and insurance is pretty good in my opinion. I've been talking to a friend of mine who owns the Panamax 5100 and says he likes it quite a bit. I know it's a little old now and it's probably been upgraded a few times but I'm looking to save a few bucks and still get something good. My wife is already saying, "what do you want to spend all that money on some box that doesn't do anything better than what you have already!". Someone please help me explain to my darling wife the virtures of having a better SS so she'll understand. What are you all using?
