Hey guys!
I have owned both the Honda and Yamaha generators. Both are fantastic. I bought the 2400 watt Yamaha because it could also power a small AC unit. I have known a few guys that have purchased the knock-offs (no names come to mind immediately, but they had a yellow case) and the biggest problem they had was getting them started. Both the Hondas and Yamahas will start first-pull without exception, or until the temp drops below 30 degrees. The others had a hard time time in nice weather and rarely started at all below 30. You can't go wrong with either the Yamaha or the Honda. The Yamaha is about 3 decibels quieter. Neither are cheap.
