You could run the whole house on that. But only if you use basic household appliances. Don't run the dishwasher and the microwave while watching the TV and surfing the net. A few lights, Refrigerator, sump pump, one outlet for the TV and internet is all you need.
Seems this site has one that might fit the bill.

I'm not sure why Smith&Wesson would follow a company like Taurus in regards to this cartridge combination. Ruger would never put out a firearm just because it's "vogue". Although the 327 and 480 cartidges are useless.
