I pretty much guaranteed I will never need a backup generator. Where we live, the power only goes out for a few hours at a time, if it ever goes out. Two years after Sandy hit us, I bought a small 4k watt Harbor Freight genny. Since then, we haven't had a outage that lasted more than 20 minutes. My thought for buying it was so we can have heat in the winter, or at least have a couple of fans going in the summer, and keep the fridge going. I do run it every few months to keep it in shape, and change the oil. The same one own, is now over $100 more than when I bought mine. I could never justify the cost of a whole house genny for where I live.,,
