Hi - can someone talk with me a bit about the pros and cons of the Hearthstone vs. something like a Vermont Castings? The particular stove I'm looking at is older, a Hearthstone II. According to the owner it's been used only about 20 times and now they want to sell it. I believe it was manufactured/tested in 1981, which is a little bit of a conern, but maybe shouldn't be. A picture of the stove is attached. They said it was $3000 new are are asking $1500.
