I've had good luck with Tripp Lite Isobars. They also make Isolation
Transformers.

I had a similar problem a few years ago, when during a violent storm a tree
landed on the cables going into my house and caused one of the "hot" wires
to come into contact with the common (I'm not quite sure of my terminology
here). I measured about 210 volts in half the circuits in the house, and
about 4 volts in the other half. My stereo amp, TV, and microwave were all
fried. The power company (Detroit Edison in this case) promptly fixed the
cables, but my insurance company covered the damaged appliances (minus the
deductible, of course).
This is the only problem like this I have ever had in over 25 years of home
ownership, so I don't know that it happens "all the time". I haven't taken
any special precautions since then, other to put UPS's on the expensive
stuff (stereo, PC).
