I bought the Ryobi RYI2200 a few weeks ago. Haven't used it in earnest so I can't I give it a thumbs up or down but did take it for a short test ride and it seems to work well. Came in at about 50% the cost of the Honda eu2000. We're mainly full hookup folks we plan on using it for emergencies mostly.
