I like the idea of a whole house protector that includes cable and phone surge protection. That and a point of use type protector at each piece of equipment.
We had a nearby lightning strike sneak into our house via the outside overhead phone and cable lines a few of years back and it really raised hell. It damaged the pairs in one of the phone wires in the basement and burned up a cordless phone base in the upstairs bedroom as well as our kitchen wall phone/answering machine, a 56K modem PC card, a small APC UPS unit and a couple of older 19" CRT TV’s. Our HO insurance paid the claim promptly, so at least that part went smoothly with no hassles.
I notice that most if not all surge protector manufacturers claim that in addition to the regular warranty, their product usually include some rather substantial amount of insurance protection against damage or loss, but has anyone ever actually collected from these or are they just a marketing tactic?
