Interesting thread. I was in the same mindset as the OP about 6 months ago. Had a Champion 3100 inverter generator I purchased new for $750 which would easily power my 13.5k a/c with the ECO mode on. After using it a couple times decided I wanted something quieter.
Purchased a pair of new Honda EU2000i's for $1900 online. Much to my surprise, they wouldn't start the same 13.5k a/c unless the ECO mode was off! Two EU2000i's running full-time with the ECO mode off are not exactly "quiet"--probably approaching the loudness of a Champion 3100.
Long story short, I'm back to the Champion 3100. Sold the Hondas on CL for $1900. I tried, but no-go.
