According to what I've read on the net the Surgex products etc. are supposedly something other than a mov but do the research and see if they'll give you any protection you don't already have. ONe guy I've read on the net has a mastering facility in Florida and has I believe the Surgex whole building spike protection. HE says it saved him some money during the storms last summer. Might be some articles on his site about it. Check out www.digido.com and see what he says. If I recall correctly he put up some comments about his system. I guess the summer before he got bit by some spi8kes thanks to lightning and had his electrical contractor install one of these when the insurance paid off for damaged gear etc. THis is all hearsay though and I'm the world's biggest curmudgeon so do your research carefully before you go ahead and beware the snake oil salesmen. 73 de nf5b Richard Webb Electric Spider Productions "They that can give up essential liberty to obtain a little temporary safety deserve neither liberty nor safety." --- Benjamin Franklin, NOvember 1755 from the Historical review of Pennsylvania
