Wen model 56380i - 3800 watt inverter generator. Bought in March, took it out of the box, removed the mounting plates (used to secure the generator during shipping), took it down to the basement, and it hasn't moved since! Never connected the battery or added gas or oil. Concluded that it would require more work to use & maintain than I would be willing to do. If you're more of a "do it yourselfer", this may be the deal for you! Check the price for this model on the Wen website and Amazon and you'll see what I mean. Still have the box it came in and everything that was in it (owners manual, mounting plates, tools, etc.).
