Holy crap. Those AFFORDABLE POWER gensets look awesome. I know of one person who's had one of the Chinese generators for about ten years, and though he complains a little about the lack of regulation (when he adds loads, there are temporary voltage and frequency sags), he doesn't have any reliability complaints.
But with these gensets running even slower and just as efficient (1gal/hour to supply a 12kW load is excellent) and being a much more established Detroit Diesel prime mover...
Get one of these.
