I am trying to determine the better choice with the limited information I have available in an classified sale. An old (date unknown but I know it's not new) Vermont Castings Resolute with a coal shaker installed, or an old VC Defiant? They are both non-catalytic. If they're in comparable condition is there a more clear choice? I've attached a pic of each I was given by the seller... My purpose is for wood heating my home of approx 1200 sq ft, fairly open floor plan. Our winters are November through March getting down to teens in an average winter. I don't have a whole lot preferences just hoping for a clearer choice. The resolute is for $400 and the defiant is for $250. Any suggestions? Thanks!
