I was able to get a portable generator during our big flood in 2008 and it was a lifesaver - I had to use it again last year for three days after a big storm that caused massive power outages due to downed trees. I can't say enough about what peace of mind it brings to have it. It's costly to run (over five gallons of gasoline a day), and it doesn't power the whole house, but it keeps the essentials going.
