Someone is advertising an older model Mansfield on NH craigslist for $2000. Its been posted several times over past couple of weeks. I e-mailed her and suggested the price might be too high considering it was an older model. I explained about pre-EPA and post -EPA stoves and how that would probably impact re-sale value. I asked her to check out the stove and find out what year it was and she replied saying it was a catalytic stove. Doesn't really matter to me, but I wondered whether she was confusing secondary burn technology or if Hearthstone at one time did use catalytic technology in the Mansfield.
