I have the Champion 3500/4000 and I love it. Over five years old and well over 1000 hours--more like 1500--and it continues to start on the first or second pull. I no longer bother to store it inside, it sits out in the winter weather just waiting for the opportunity to be of service. Every few weeks I'll give it a half-hour of exercise and make sure the gas has a little Seafoam in it. IMO, it is a marvel of practical technology.
And it is 100 lbs of bulky, day-ruining weight.
When looking for a LIGHTER-weight, inverter gennie, I figured I'd get the CPE 2000, until I read the posts. I didn't want to have to parallel two gennies just to power the basics, and the units were still that bulky, difficult to heft shape. I realized I really wanted a 3000-class gennie.
After research, I took a chance on the Powerhouse 2600/2700 for $1,000. This is a suitcase-shaped inverter gennie that will stream 2600 watts all day, similar to the Honda 3000. It is 80 lbs, and because of its narrow shape and carry handle it is reasonably luggable. It also comes with a completely useless set of wheels and drag handle, which I removed.
The sound is much less annoying than the Champ, at least according to the comments I've gotten. It is a much lower note, and somewhat quieter than the Champ. The eu3000 actually sounds more "clatterey" in comparison, although I think it is still a bit quieter than the Powerhouse.
I would definitely recommend this gennie, both for its cutting-edge design and its reliability. I would note that in the very first shipments there were comments about some gennies arriving DOA. I bought mine from Cabela's (with its rock-solid return policy), and I plan to buy my second one there, and a parallel kit. Just as soon as I can figure out what to do with 40 amps continuous output!
