We have a Harman advanced it was here when we bought the house in Dec 2013. (they had it installed in 2009) In 2016 we had to replace the auger tube and now it's cracked again. They are recommending we buy a new stove an XXV or Absolute 43 either one with the install is close to $6500 not including piping. Is this good pricing? Are there certain brands I should be looking at? Any advice would be appreciated.
