So you may have seen my thread about swapping out our wood-burning insert for a pellet insert. With that in mind we went to Preston Trading Post today to check out the offerings. We looked at Mt Vernon AE, Castile, and Enviro M55 insert. We walked away very impressed by the Mt Vernon AE, incredibly quiet, especially when compared to our Lopi Freedom. We are still planning on looking at the Harman Accentra, but are currently sold on the Mt Vernon AE.
