I am buying my first ever pellet stove at 60 years old. Harmon P61a and am looking forward to learning as much about pellet burning as I can. Average oil cost in the last few years was $3000 for the winter. I am sure some of you have this stove so let me know how you like it. Also will be looking for a small used one for another application. Thoughts on what brands to look at for used. Thanks.
