Since I've ran out of time on building a masonry wood stove. Thinking something like design #2 http://www.tripletrick.com/kachelofen/galery.htm
we've decided to go third world for the winter. I will be building a Cob oven in my present fireplace extending out on the hearth. I'll stick some stove pipe in the back of it to go up the chimney acting as a flue liner. (I have to rebuild my chimney with a liner for a masonry wood stove). It should be fine for one winter, we can sleep in the living room if its not warm enough to heat the house. Cost will be stove pipe, scoop of sand, bail of straw. Likely supplementing some heat with present gas system.
Here's a simple cob oven for outdoor cooking. You have to build a door with iron and fire brick to put one in as I described.
