Generac has a very good reputation around here in the inland northwest.
I went with a Harbor Freight 9000-watt gasoline unit that runs my place just fine.
Not as convenient as the automatic deals, but not a big problem for me.
But I don't use much electricity normally, and less when the generator has to supply power.

FWIW, when the utility company graced us with NG, they had to install a bigger commercial meter at my place.
My back shop is about 100' from the meter, which is 270' from the line in the road.
NG heats the front & back shops, and supplies house furnace, stove & clothes dryer.
