I have struggled with this purchase for a long time and finally bought a Honda eu2000 generator. This was tough trying to weigh out how much power we need compared to how much fuel we are will have on hand in an outage. The 2000 watts will not run our deep well pump so no water but I can keep the food from spoiling and the fan running on the wood stove. This generator will run 10 hours on a gallon last year I borrowed my bosses generator his was large enough to run the well pump but I went through 5 gallons in two hours. I just don't see that as being practical in an extended outage. I am still trying to convince myself I made the right call.
