~35/day split between 3 roommates aint too shabby... probably about as much as our regular energy bill after those fricking fuel adjustments
Very well worth it. Only ran about $30 to $35 a day for a 15KW using natural gas. Automatic transfer switch. Generator cuts on automatically when power goes down. Oil change required every year or 100 hours of run time.
It's the money you spend hooking this up that can get kind of costly, but I think it's still worth it. You buy a generator and hope you never need to use it. But it's there in case you do need it.
