I found a used Quadrafire outfitter II pellet stove on facebook market place for sale. He says it needs a new control board. The model is CAB50..He is asking $450 for the stove. Is this a good deal or to high since it needs a control board. He told me under $200 for a new board. Been looking online and I don't see any that cheap. Most I see are around $260. What do you guys think?
