Yes I have a recommendation, from something I learned the hard way. Look at the Total Harmoic Distortion (THD) output from the generator. THD kills sensitive electronics, like oven and refrigerator controls, digital thermostats, new digitally controlled washers and dryers, the control panel in modern furnaces, anything digital. THD is often what makes two generators of the same size vary in price by a huge margin. Good generators that are make minimal THD like under 5% are pricey. Generators that make more than 10% or more THD tend to be much more affordable in price on the front end. When I was researching generators, I was so focused on watts, and running watts, and surge watts, and I had no idea THD was a thing or to even look for it. It is labeled for every generator, somewhere either on the generator box, in the manual, on the manufacturers website or on the side of the generator itself.
