Having worked on stuff with some massive surge protectors, I'd say that surge protectors in a Radio Shack (or any other store) are like having an umbrella compared to a regular rain storm. The higher end stuff, up through this brick wall, are kind of like variously well built buildings and storm cellers against increasingly nasty storms. And lastly, there's the direct lightening strike. Which fries everything within a certain radius. It's equivalent to a tornado touching down exactly against your storm cellar, and maybe even dropping a locomotive right through the entrance as well. And if that's not enough, there's always a meteor strike to ruin your day. Don't get me wrong, I'm all for protection, I've just come to realize that everything is in shades of grey. But I do agree that those MOV based surge protectors are pretty much worthless, like bows and arrows agains the lightening (it's a cloudy, stormy day here in Chicago, what can I say...) ---------------------------(end of broadcast)--------------------------- TIP 5: don't forget to increase your free space map settings
