I am rebuilding my Defiant Encore (Vermont Castings) Stove and have realized I need to replace the combustor as well. After sticker shock for replacement catalst I started checking around and found alot of different options were now available for my stove. Now I'm really confused, Steel. ceramic , the Applied ceramics co. or Stovecombusters.com, I don't want to experiment but think their is more than just OEM options. Any comments or ideas would help alot, It's cold and I need to get the stove running, Thanks, Tom
