about to purchase this stove. Does anyone have or previously had this stove? Just wondering your overall opinion on it. Just looking for any last minute reviews/suggestions before I spend $4k for stove, liner, labor, etc. Any useful tips? With a 2.9 firebox, how many pieces of wood does it use on 1 load? What is the maintenance? How are the burn times? Fan loud or relatively quiet? any info is helpful. thanks.
