We just purchased 2 Honda 2000 watt generators with the parallel kit for $2300 and they give us 30 amps - enough to run our 2 A/C's and TV, satellite and lights.
They are really quiet, but it does require us to keep gasoline on hand. Cheaper than an Onan permanently installed, and about 200 pounds lighter.
Just my 2 cents worth.
