For what its worth, I bought and installed this Square D surge suppressor:Shop Square D Load Center Hardwired Surge Protection Device at Lowes.com It was inexpensive and relatively easy to install - if you don't mind getting into your electrical panel Supposedly it will protect the entire house from a lighting strike. I had looked into these a while ago, but the were much more expensive. Obviously they have dropped significantly in price. The electrician at Lowes recommended to replace it every three years (I put a reminder in my phone.) It has an idiot light to tell you it is still working.
