you can get the gen with a perkins or laidong engine.Supposedly the laidong engine has been around for a long time and has a good history of reliability .Also they use stamford alternators.
Would that be a liquid cooled Laidong engine?
I know that Chinese engines have been improving over the years. Whether they're in par with Kubota, Yanmar or Isuzu, I don't know.
I know that $5K for a 9.8KW Kubota is very good price. I paid that for my unit at camp 30 years ago! As a matter of fact, I have a contingency fund in US dollars set aside to buy another Kubota probably from Central Maine, if my present machine ever expires.
Personally, if I were living in your part of the continent that has such severe weather and power outages, I'd be looking at the best quality I could afford. A lightly used, well maintained Kubota, Isuzu or Yanmar powered generator would be my preference if the price will be close to a new comparable Chinese unit.
If you're comfortable buying a Chinese powered unit, go for it and let us know how it goes.
