Anyone here have one, pros, cons? What was the purchase price for the unit if you dont mind sharing? I am looking around at the flush units and need something affordable (3k) is above the budget and this one looks really slick. If anyone knows of a brand of flush insert that's below 3k feel free to jump in. Thanks in advance. My house is 1800 sq ft split level with fireplace on main floor interior chimney, open floor plan. Opening is 36w 25t 20.5d the back of the box is 25.5w
