This commercial grade, affordable gas powered 6000 Watt generator by the Chinese giant, Lifan is well worth taking a look at.  For under $1000, you get good, clean, reliable power in a sturdy well-designed unit.

Anyone who does not want to line up at the gas pumps when the big storm hits, may want to consider the Generac 6000 LP3250 Liquid Propane Generator for the easy convenience and long-term storage of stable, clean-burning propane.   There are lower emissions than for gasoline, but the fuel stability over months of storage means that you can be prepared a year ahead of any power outages.
