Looking For A Quiet Portable Generator?

I am constructing a 10ft x 12ft Arrow steel storage shed in the Spring for my model train layout and I am looking for a portable (if possible) quiet generator that either runs on an eternal electric battery or use gas. The generator will power the layout and the lights. I read that inverters work great, but... show more I am constructing a 10ft x 12ft Arrow steel storage shed in the Spring for my model train layout and I am looking for a portable (if possible) quiet generator that either runs on an eternal electric battery or use gas.

I read that inverters work great, but there might be a lot of brands who make them. I am wanting one around the $200-$600 range. What is the better brand(s) to look into and/or buy from?
