Who has a back up generator (permanent install)

Hey Mike... don't have one "yet" at this house. My Dad had one at his place. I had an estimate done for a 22k propane whole house with distro switch box was for about 10k installed. My Dad loved his Generac unit. Hooked into the natural gas line. Test start and run (automatically) every Sunday. Almost zeo hiccup when power dropped and the generator kicked in. You'd never know you were on generator power. Very quiet even right outside the window.
