CPO via eBay offers the refurbished Generac iX2000 2,000-watt Portable Inverter Generator, model no. 6719, for $349.99 with free shipping. That's $180 under the lowest total price we could find for a new one. It features three outlets, a 0.83-gallon fuel capacity, 2,200 watts max power, and pull start handle.
A 90-day warranty applies, although it's unclear who supports it.
