Difference in honda generators Big store vs small dealer?

You will not find much of a price difference the prices are fixed by Honda. The only difference may be service if you were to need it which may be better at a small shop. Parts are available on line. I have three of the 2000I's one of which is the companion model all were purchased on line and have never needed any service that I could not do myself such as oil changes and cleaning the air filter , changing the spark plug also changed one carb and one muffler , over 12 years of using them. Great machines
