Hello rxb, welcome to the forum... Just a note on inserts.. you will get a lot more heat out of a free-standing stove. An insert's back, sides and top are at least partially hidden in the fireplace, and the heat raditated to the inside of the fireplace is wasted heat..
I know that inserts look nicer, and often space in the room is an issue. But if you are concerned about the efficiency of getting the heat into the house, an insert is not as good as a free standing stove.
The Hitzer is a great stove, as is the Harman... If the Hitzer will fit and work in your fireplace, I'd go with it. They are very well made, and have excellent after the sale service from the factory if needed. The hopper feed design is great, and makes feeding the fire much easier in a low fireplace location. Keeps the mess/dust to a minimum.
Hope the above helps. Greg L
