If you want to consider buying a used one to save a small (yes small) bit of coin, check out some local camping sales dealers in your area, or camping forums, as quiet generators are very popular with the camping crowd.

However, because of their popularity, they hold a strong resale value. If you are able to score on one for a reasonable price, consider yourself very lucky!
