This is the woodstove we have been using for over 20 years.
It is the Coalbrookdale "Darby" model. It is heavy cast iron and rates 2200 btu of heat. It has a removable ashtray so you never have to let the fire go out, and a flip-open cooktop, which can come in handy for making soup, coffee, toast, and other food in case of a long blackout where you don't necessarily want to fire up the backyard grill. It's got the glass doors so you can see the flames, and it also comes with a handy coal conversion kit (although we have never used it since we're in the middle of the woods and free fuel is plentiful).
Great stove, I highly recommend it.
