I am in a region that gets a lot of severe weather especially thunderstorms with multiple strikes of lightning in the general area. I have had to replace two surge protectors but not any of my big high dollar items. I would say that yes the surge protectors are a good idea to have. But you have to remember Murphys law of electronics. "A $300 part will always blow to save the $.03 part."
Remember lighting strikes occur often on p[hone lines also so ensure to protect the electrical and phone line and unplug your computer when not in use on the internet.
Ensure the protection in on all three wires black white and green (ground).
