Debating again if i should spring for a fireplace insert and get away from the heataltor fireplace that does more harm than good in terms of heating the house. What I am looking at now is the quadrafire 2700i insert that goes inside the firebox of the current fireplace, but the cost is pretty steep ($4k). Its a small unit but looks like it would do ok. Anyone have any first hand expirience with this kind of set up? . . . . thanks
