My friend has a wood stove insert he is not using, it came with his house when he moved in. They switched to gas logs so they want to sell the insert. I want to buy a nice used insert for my sister's new house. The model they are selling is a Regency R16. He said is has a blower. Does ANYONE know ANYTHING about this stove? Estimate it to be approx 12 years old but little use. Any idea as to the worth, efficiency, etc. would be greatly appreciated. Thanks!
