I was thinking about a standby generator, but I decided not to because of the fact that im not interested in the complexity. I know a few people who have them and all have told me stories about having stupid problems with them. Like leaking coolant, or the automated switch failing...just crap ill never have to deal with using a portable generator. . Plus I like that its mobile if I need to use it elsewhere for whatever reason.
I bought a 6600w generator and it was more than enough at my house. I have an electric hot water heater/forced hot air and the hot water heater was only thing to bring it off idle. I also installed a 6 circuit transfer switch. For my house I might change it to a 10 in the future since 3 of my 6 are used for hot water/furnace. The other 3 run my kitchen, living room, bedroom/bathroom. Now if my power goes out, just move the generator outside, plug it into the transfer switch, start, return to television. It ran from 6:30am yesterday until 7pm on 1/2tank of fuel, about 3.5gallons.
