Looking to up grade my sante fe insert for more heat and less noise.to loud on high. (QUADS) Went and seen the guy I bought 2stoves from over the years righteous guy.He pointing me towards the mt. Vernon said i won't be disappointed,quite, more heat, less work.I Kinda think simpler is better which is why i dont like it.He had the 1200i there also said the heat on medium would be like the heat I get on high with sante fe similar noise. . (LENNOX) I stop at a store I'd never been to and the guy showed me a Lennox Winslow and fired it up.I tell you I was surprised no tink tink when the pellets were feeding like the quad makes. It put out some nice heat, noise was reasonable low.Dont know much about the manufactor,seemed ok build. . (HARMAN) The guy also sells the m55 but didn't have the insert on the floor.The Harman insert was nice. Look and felt well built.He favors the Harman over the m55 but said he would get me what ever I wanted.seems like the Harman is a real nice insert. Oh we'll that's it for now.guess I will go soak the foot.
