I am looking into purchasing a Federal Air tight model FA288CCL. It was bought in 1985 fir $2200 and has only had one owner. He has never used coal only wood in it. It does not have a blower but is set up so that one may be added. The man said he used it as only heat source in his house with -40 temps and had great success but has since moved to a smaller house and it is to much stove. He is asking $600 and I am looking for some insight to if this is a good model and if this is a resonable price.
