What Wood Stove to Buy?

Just bought a small house in Bristol, Tennessee. In case the power goes out, I want a backup in the basement where there is an opening in the chimney for a flue. No fireplace, must have been an oil heater there once. House built in the 60's, block walls from basement to roof, apparently not insulated. Good insulation in attic.

The chimney looks good, 9" terra cotta liner, clean as a whistle.

I like the efficiency of the front-loading longish stove (Euro style, apparently) or a downdraft unit, which also has good efficiency. EPA approval is a must with the insurance company, and they have secondary burn.

Of course, price is important. I really want to stay under $1000 on this. Any recommendations?
