Ok, we are building a new home on 8 acres. 2300 square feet ranch. Propane furnace so looking for a pellet insert to keep it toasty. Note, I'm a city boy a always had natural gas. I have no desire for a wood stove or stand alone pellet stove. We are going to have a firebox and then have an insert installed (corner). I know I want to get one of the inserts that qualify for the 26% credit so it looks to between the Trekker, the 52i or Lopi AGP insert. I know so little about these that I want something that is easy to clean. The dealer I prefer only sells the AGP. This guy has been in business 20 years and his son is soon taking over. The other dealer which sells the Harmon 52i and the Trekker didn't seem to care much for my business and his reviews indicate that once the product is installed I'll be on my own. Any advice? The AGP was recently redesigned this year per the dealer and will run about $4800 for the unit. The Harmon 52i was at 5400 and the trekker at $5100. Thanks!
