While very, very tempted to try a Champion, I went with the Honda EU2000i Companion. It was only 30 bucks more, and I see the 12v charging option of a base EU2000 as superfluous. The twist lock 30 amp connector is the same on my 6,500 watt frame generator at the S&B, so that doesn't bother me. Besides, I bet I could reach in there and swap out the locking 30A receptacle to a RV style if I got really bored one day (probably while I'm securing a steel base plate to it for security).
Honda was my second choice behind Yamaha, but I couldn't conveniently, in a reasonable time frame, procure the Yamaha. That set the tone for future customer support from Yamaha.
Fudge it. I got a Honda and I've had zero cognitive dissonance about it. I plan to use the heck out of it camping, at the S&b, as well as on job sites and not replace it for a long time. I also like the convenient arrangement for adding an an auxiliary tank. I purchased it at a local Honda dealer I've patronized for 15 years. The Commonwealth of Virginia had a Hurricane Preparedness Tax Vacation for a week in May, which saved me 5.5%. The dealer also waved their standard "Start up/Pre-delivery Inspection Fee" (they put gas and oil it, then start it up) of 50 bucks. Out the door for less than $1,000 and I supported a local, family owned establishment.
