Honda. Buy it once, and never buy another one again. Buy the Cheap-O Clone Gen, and you won't be happy. How do I know? Experience.
Few years ago, I bought a 3500w Wen Power Gen from Pep Boys. Quiet, starts right away, 6.5hp Clone. It struggled with a small air compressor, 2 Halogen lights, and 2 fluorescent lights. So, I bought a Homelight 6500w with a Yamaha engine. It was better, ran the above fine, but it will drive you nuts if you have to be by it for more than 10 minutes. Want to buy either, will make you a package deal on both. A buddy has a 6500 watt Honda on wheels. It was running at the track and I went to look at it before I realized it was running, I was shocked at how quiet it was. BUT, the Honda's will run the advertised watts, the Cheap-O gens will run about 50% its a good estimate.
