My power company is offering external surge protectors (Storm Safe) for a $25 installation fee (waived if customer agrees to a 3-year service contract) and another $6 a month to have it. I wanted to know if it was worth it for the infrequent surges that occur and maybe how effective it is. More info on it here:
I don't know if it is worth it or not. I don't like the idea of a monthly service charge. Modern appliances have electronic controls that could be sensitive to a lightning strike. I'd suggest you post the question to the electrical forum at www.handymanwire.com.
I'm a strong believer in the internal surge protectors for electronics and I have several. One is a combination surge protector and battery backup for this computer; it will hold the computer up for a brief power outage so I can shut down whatever I am using and save data. It is something you would get at a computer store.
The others are simple surge protectors on power strips and the like; you can get a single outlet type from Belkin for about $10. I like them to protect computers and TVs from a power spike caused by a nearby lightning strike.
Figure that even with underground utilities, the power has to go underground somewhere and that could catch a lightning strike.
A question I have - that wasn't answered in the link you posted - is what kind of warranty is offered on the external device. That is, will they replace an appliance that is damaged with the SAME quality appliance? Many of those appliance warranties will only replace an appliance with what THEY call an equivalent appliance, that you may not like.
For example, Belkin offers a warranty on their single outlet internal surge protectors. The company has been around for quite a while and while I have never had a claim against them, I would expect them to be honest in dealing with you.
On the internal devices, realize that there is no way they could replace lost data on your computer; you really are on your own there.
