Ok we had a whole house surge protector installed when we moved in cost a couple hundred I think. We just had alighting strike a few weeks ago hit a tree next to our house. The surge when down the heart of the tree and into the ground and it found our cable line. We lost a lot of electronics and garage door opener but I think the whole house surge protection protected our appliances. Anyway since the company for that system is out of state and from what I have heard hard to deal with for claims we just the other day had Seco install their surge protector outside. Cost $25 for the install and $5.95 a month and they maintain it. Worth it to me plus they give you some protectors for electronics in your house. We also went out and bought some major surge protectors for our TV's etc. we made sure they had connectors to hook our cable lines into and phone line. One of the ones from Seco has this plus they sell them on their website. Anyway after our experience we did as much as we could to minimize damage. Oh and our AAA Ins covered everything and in less than 2 weeks
