I found a 7 year old Hearthstone Mansfield for sale on Craigslist., about 2 hrs from home . The owner says it has never been over fired. To be sure , what should I look for? Outside of the obvious like warping or cracks, is there a life span on the secondary tubes ? He's asking $2000 or best offer, I'd offer $1500 because I would want to replace the secondaries if needed,
