The discussion on this got me to dragging my feet. I did go to Furman's site and I do see that Sweet Water is an authorized dealer, so I think I am going to call them and order a PST-8 from them, and it will be better protection than what I have now, which is no surge protection.
I will say that so far in my life I have NEVER experienced any type of surge activity that damaged any of my components, and once upon a time I never even used to unplug my gear during thunderstorm activity--I was happily oblivious.
But there is a first time for everything. I used to eat six raw eggs a day, and when someone told me about raw egg salmonella I scoffed at that person. I told him that I must have ate ten thousand raw eggs and never suffered so much as an upset stomach. But then I thought about it soime more, and I decided that as many raw eggs as I had consumed in my life, I was probably due to get a bad one. So I don't do that anymore. As far as my system goes, for the immediate time being it is physically unplugged from the wall when not being used.
