Home Depot offers the Sportsman 7,000-watt Portable Gas-Powered Generator, model no. GEN7000, for $499 with free shipping. That ties a deal from two weeks ago and is the lowest total price we could find by $100. Powered by unleaded gasoline, this generator runs at a continuous 6,000 watts (7,000 surge) and features a recoil start or electric start (via a motorcycle battery, not included) and 7-gallon fuel tank.
