I am going to pick up this Pacific Energy Super Series Insert tomorrow used. I am paying $600 for it and it is 5 years old. It has an upgraded blower and everything looks to be in decent shape. I have a 1500 sq ft Bi-Level with my fireplace being in the basement. This thing should heat most of my house I am hoping. I have attached some pics below what do you guys think? Decent deal or what? Opinions on the condition?
