Does anyone own these and have any info on them? I saw them in the catalog and my local dealer doesn't carry them or know anything about them. They are half cast iron and half steel with a top load door. I really like a top load stove and I've always had a stove with one and there doesn't seem to be many with that feature these days. The half steel and half iron really intrigues me and I am wondering how much cast iron on the stove there really is? Is it substantial or just decorative?
