Getting ready to pull the trigger on a new Insert. I bought the Sante Fe in 2005 and it has been bullet proof. Run about 3 1/2 tons threw it every year, never had a problem, just small stuff jam here and there it's been great. Wish it could do better on those real cold February nights. Thinking about either the Harmon accent insert, or the m55, or Cb1200i for a little more heat. Any Advice Greatly Appreciated .Thanks A Bunch
