I am looking to buy a backup generator for this winter in case the power goes out during a storm. The past 2 years here in CT I have been lucky that downed trees have not taken out the power in my neighborhood in a blizzard. But the odds are it will happen at some point. I am looking at Coleman 5500 amp models or similar models. Is the Coleman brand any worse than similarly rated amp brands? What is the best generator for the 5500 amp range?
