Home Depot offers the Stanley 3,250-watt 173cc 6.5-horsepower OHV Portable Generator, model no. G3250S, for $314.30 with free shipping. That's tied with last week's mention as the lowest total price we could find by $21. It produces a 3,250-watt surge and 2,250 watts of continuous power and features a 173cc 4-stroke OHV motor. It runs for up to 2.5 hours at a 50% load on 2/3rds of a gallon of gasoline.
