Hi. First post here as I’m in the market for a pellet stove. Interested in a stove for a 3000 sq ft house. Looking into the P68 and wondering what a reasonable used one should sell for. Have my eye on one and they’re asking $2200 saying the board and ESP just changed. Looks in decent shape based on pictures. 2006 date. Also, and looking at the pictures, I don’t see the availability for a fresh air kit. Thanks much. Jim
