If I lived in a location with lightening I would probably install someting like this on the power to my equipment.
The problem around here is you don't always know when lightning will happen in advance, and certainly don't' know a transformer just got hit by a car. I mean, sure, when a big storm rolls around I turn my conditioners off and sometimes even the breaker, but lots of times lightning has come out of nowhere at 3 AM around here.
One of the stupid surge damages I used to suffer from was WIND storms taking out my DirecTV. Apparently the excess wind would deposit excess electrons on the antenna surface and ZAP! Out goes my satellite receiver. Good to have high quality coax protection as well.
