It won't surprise anyone here that I would say go for the Harman. I have 2 of them, one of which is on it's 17th season of operation. They are very few of us here that can say they have run the same stove for that long. The PC 45 has a different burnpot with a "stirrer" in it to keep things "moving" in the event you are burning corn or some other fuel. It is considered a multi-fuel stove. I had one for 3 weeks, absolutely hated it and returned it for my present P61A. Looking back on it now, I probably had a lemon, which is extremely rare in the Harman world as there are many PC 45 owners here that are very happy. The stirrer runs quite often "grinding" up the ash, keeping the burnpot cleaner, longer. If you are going to leave the stove for several days, even with a big hopper you will probably run it out of fuel depending on the time of year. A Harman is the Caddilac of stoves. Its a true "you get what you pay for" purchase. The bottom feed auger, easy automatic operation, less frequent cleanings than some others, and overall quality of the product is what is making your poll numbers show Harman. Good luck, whichever stove you choose, and welcome to the Forum. P.S. I am a charter member of the HarmAn spelling Police.
