Someone at the mac store in arcata, ca, told me something like eight years ago that if I was really concerned about lightning strikes I should get a voltage meter (or regulator, I forget the exact words). I declined.
We didn't get much lightning in our old neighborhood so I was spooked about it when I moved to that area.
@ossobuco,
An outlet surge protection is dirty cheap and offer some protection at least.
A direct or near lightening strike is a horse of another color and a UPS running all the time is the only way of offering even fair protection from such an event.
