Be sure to read the
announcement at the top of this forum. Then narrow your selections down to specifications that suit your needs. Finally scrutinize the dealers in your area and see which ones are motivated enough to sell.
For what it's worth I considered a Harman for its specifications but the closest dealer to me didn't impress me with his professionalism. The Harman seems like a quality unit but I was reluctant to buy one without competent local support. The Quadra-Fire I eventually bought was available locally, but the dealer was difficult to work with and didn't seem terribly knowledgeable about the stove. They wanted a $1000 deposit from me before lifting a finger, then sent an installer to inspect my site who proceeded to tell me all the things he wasn't willing to do. I ended up buying one from a dealer farther away, who expressed genuine interest in my requirements and answered all my questions in a professional manner. Their price was even a bit less.
You can buy the most well-engineered product on Earth but if it's not installed or serviced properly you'll soon regret your decision. A pellet stove isn't a frivolous purchase for most people. It astounds me that manufacturers of quality equipment would let nincompoops represent their company at the retail end.
