it seems like you know more about these stoves then I do. Whats the difference between the new EPA style stoves and the older ones? I don't have a problem paying for a newer one, I just want good ones without the catalytic style since we don't burn the highest quality wood here.
I have more wood than I know what to do with and have to heat a poorly insulated 8,000 square foot building with 30' ceilings
8,000 sq' with 30' ceilings you need more than a couple stoves.

Ever think about an outdoor boiler? I'm not a huge fan of them but for that type of square footage you'll be doing nothing but feeding stoves all day. If you have money to burn a nice gasification style boiler with some water storage would be really nice.
I'm too Lazy to type the difference in EPA stoves out so here is a copy/paste from here.
http://www.epa.gov/burnwise/woodstoves.html For what you're doing I agree with staying away from a stove that uses a cat.
Types of Wood Stoves
The two general approaches to meeting the EPA smoke emission limits are non-catalytic and catalytic combustion. Both approaches have proved effective, but there are performance differences. Although most of the stoves on the market are non-catalytic, some of the more popular high-end stoves use catalytic combustion. Because they are slightly more complicated to operate, catalytic stoves are suited to people who like technology and are prepared to maintain the stove properly so it continues to operate at peak performance.
Non-catalytic Stoves
Non-catalytic stoves do not use a catalyst, but have three internal characteristics that create a good environment for complete combustion. These are firebox insulation, a large baffle to produce a longer, hotter gas flow path, and pre-heated combustion air introduced through small holes above the fuel in the firebox. The baffle and some other internal parts of a non-catalytic stove will need replacement from time to time as they deteriorate with the high heat of efficient combustion.
Catalytic Stoves
In catalytic combustion, the smoky exhaust is passed through a coated ceramic honeycomb inside the stove where the smoke gases and particles ignite and burn. Catalytic stoves are capable of producing a long, even heat output.
All catalytic stoves have a lever-operated catalyst bypass damper which is opened for starting and reloading. The catalytic honeycomb degrades over time and must be replaced, but its durability is largely in the hands of the stove user. The catalyst can last more than six seasons if the stove is used properly; but if the stove is over-fired, inappropriate fuel (like garbage and treated wood) is burned, and if regular cleaning and maintenance are not done, the catalyst may break down in as little as 2 years. (EPA note: Garbage should never be burned in a wood stove or fireplace.)
