A few comments about comparison with the eu2000i. If the Prof's resistive load test is representative of the "Typical" CPE 2000, I say it cleanly beats the eu2000i in this regard. I don't recall ever seeing a report of an eu2000i achieving a 1,900 watt output. Mine peaked out at somewhere around 1,800 (don't have the exact data with me now)at 550' elevation. As the load is increased, the eu2000i voltage stays above 124 through it's continuous rating of 1,600 VA. Somewhere beyond that, the voltage starts to droop to create a maximum power output (after a certain point, as the load is increased, the voltage goes down as the current goes up, along with a reduction of output power). A circuit breaker trip is rare on the eu2000i, with the electronics going into overload mode first in the majority of cases. With the eu1000i not having a breaker at all, I suspect the only reason the eu2000i has a breaker is to limit the current to the outlet when operating paralleled units. Observing the eu2000i on a scope shows it to be very good at handling loads with a poor power factor. It's immensely superior to an Onan Microquiet in this respect. I don't have any hard data but I suspect that it will handle more than 2000 VA, being limited mainly by the load in watts. Maybe the Champion is also good in this respect. Somebody will have to check it out.
