I've only researched generators enough to know there a LOT of caveats...

Last December during our ice storm power outage where most of the state was without power for almost two weeks, there was, of course, a run on generators at Sears (where I work, not for Sears, but for a licensed business). In the break room at lunch I talked several times to the men who were not only experienced in selling the generators, but usually had electrical or other backgrounds. None of them own a generator or will have one in their house -- for safety reasons.

That being said, it would have been nice to have had auxiliary power for our pump and freezer. We heat primarily with wood and some cooking can be done on the woodstove. We also have a composting toilet, so that's not a problem. Batteries took care of lighting & radio needs (though after a week, most sized batteries were unavailable). There are ways to recharge cell phone batteries. Being without a computer was the major pain -- and no running water. Gallon jugs from the store and I had my hair washed at the stylist's.

Just be fully informed before you buy and install.
