I have a weekend/occasional use cabin that has a Franklin (cast iron, 2 bi-fold doors) type stove installed. I really don't like the stove and would like to replace it. I stopped by my local stove store and was quoted about $4,000 - $6,000 as an installed price for a new stove. Considering that the stove is only used about 30-40 hours per year I don't want to spend that kind of money. My thought was to buy a used stove on craigslist and install it. Is that realistic? I'm sure the old one was installed to "code" in 1980 but I'm sure the stack is 8" single wall. The roof penetration and flashing look good - but I'm an amateur.
