The problem with all these inexpensive inverter generators is the lack of an extensive dealer network for parts, service and repairs.
With Honda or Yamaha, there are dealers in every town. Where would you start looking for brand specific parts on any of these inexpensive generators. We have chain stores locally that have sold Champion generators for years. Other than spark plugs, I have never seen a Champion part on their shelves.
I guess it's one of those deals that you look like a genius when it's working good, but an idiot when it's broke and parts are unavailable for weeks.
I guess you have to ask yourself if you are willing to take that chance, to save money.
