I have a Coleman 6850w that I have used every weekend for eight months of the year the last seven years. It is used at a dirt track where it is very dusty.
The biggest key is to make sure that you run the gas out of the motor after each use. Most generators have a fuel shut off on the fuel line coming from the tank. Also, if you don't use it for long periods dump the fuel and start it with fresh fuel. Change the fuel filter every year with the annual oil change.
Like you I liked the quietness of the Honda, but the price was not an option when I was buying. I did put a muffler for about $40.00 on the Briggs motor that made it tolerable.
