I have found a late 80s VC resolute for $100. The ad and the seller said that he rebuilt it, sanded it, and painted it but never used it. He bought it used and was apparently working when he bought it. He found out that it would cost him several thousands of dollars to add a metalbestos chimney to his house. What should I look for in this stove. $100? there are late 70s models of VCs that are still getting $400-$800. What do you think?
