I'm looking at getting a fireplace insert for my house. My house is a 2700 sqft colonial with a fairly open first floor. the room with the fireplace is large with 2 doorway exiting it, 1 36" into the kitchen and the other 8' into the another room with the staircase leading upstairs. I want some opinions on what you are using and how much it cost you. I looked online at the Osborn 2400 and it seemed nice, much less money than the local shop I looked at.
