The Champs are unreliable? New one on me. I see more "my Honda wont start" threads than issues with Champions.
The Champion will fry the electronics? Actually there is a scope of one of the Champion 3500/4000 120v only units in the 3000w generator thread. It is cleaner/ smoother than you would expect. Much cleaner than the inverter generator that HF sells. The dual voltage units do have a ugly wave.
I will say that after spending the money I didn't waste on the big red generator on a solar system and batteries, that it is funny to watch someone with a generator thump their chest because their noise maker is slightly less annoying than the next one.
I see people say that they would be knocking on doors if their neighbor uses something louder than they have. So what happens when a person with solar comes knocking on your door? Gee dude, I don't care what color it is, it's time to shut her down. We'd like some peace and quiet, not peace and quieter.
The problem with jumping on a soap box is there is always someone with a bigger one. There plenty of people that can go a week on battery alone or have solar. To them any generator is annoying.
