Oh - you guys are killing me - so much homework!
Thanks, everyone, for helping with your suggestions.
Looking at the furnaces, they all seem to assume you have duct work, which I don't. Got sidetracked for hours reading about the Kuuma furnaces. All good info and even if I don't use a furnace, there's lots of great heating ideas on the furnace websites.
LloydE: I checked Craig's List, and in my area there's lots of Vermont Castings and an unbelievable selection of Jotuls to choose from.
Thanks, Lockhaven, for the moral suport!
Clemsfor - thanks for your suggestions and the insight on the low burn issue. I'll have toi research that some.
Moss - thanks for the Napoleon suggestion - more to research.
KennyG - thanks and I have been considering putting some registers through the floors, upstair, to help get the heat up. Just don't want to cut holes in the nice oak flooring, but it may come to that. Have to check our local building codes, too. Basically, we keep the basement door open all the time, so a lot of the heat comes up the stairs into the kitchen and then to the rest of the house. Some of the heat stratifies under the floor joists and that tends to warm the upstairs floor in a very pleasant way, so I'd like to keep that aspect. Starting to research piping in outside air to the stove to increase chimney draw and address potential smoking issues.
