Went with a natural gas Generac 9k generator about 4 years ago.
Didn't feel we needed a whole house unit, but wanted power to all the important things we depend on.
It runs our well, furnace w/ AC, stove and ref. TV's, Computers, and about half the rooms with lights and outlets.
Comes on once a week and runs for about 15 minutes, longest it's been needed has been about 7 hours so far.
Worry more about it's need in the winter, than summer. We can live with the heat, but not the temps that will freeze your pipes. It's not instantaneous, but the very short delay only affects our digital clocks.
I look at it as another type of insurance policy.
