I don't like to start a thread just for this, but I am looking at a used Hearthstone Mansfield ((broken link removed to http://nh.craigslist.org/app/3275911489.html)) that seems to be in great shape (10 years old) and priced quite well. Not sure what to look for as person selling, although they used the stove, does not seem to know much about stoves and maintenance. Any advice and things I should look out for? Appreciate it.
