I'm looking into purchasing a 13 year old Woodstock Keystone stove. The seller is asking $1200 and the stove has the original cat. Additionally, there is a crack in the stone above the door. Woodstock sells it for $20. I was going to see if I could get the stove for what he's asking, less the cost of a new stone and cat; so about $1050. I figure at that point the stove still comes in for half of what they sell for new. Does this sound like a good deal? I really like the Keystone, I don't want to pay for a new one and they aren't that common in the second hand market place.
