Today only, Home Depot offers the Smarter Tools 3,500-watt Portable Gas Generator, model no. STGP-3500, for $199.99 with free shipping. That's tied with our mention from a month ago as the least expensive 3,500-watt gas generator we've ever seen. (It's also $127 below the lowest total price we could find for a similar generator elsewhere.) Sales tax is added where applicable. It runs for up to ten hours at a 50% load and features a 6.5-horsepower engine, 3.6-gallon fuel tank, and low-oil shutdown system.
