I have the 400 woodsman model. Bought it last November, just in time for the coldest winter here in 30 years. I haven't had any issues with the stove, just a minor issue with the circulator pump, but no biggie. I love not having to buy propane anymore saved at least $2500 in propane last winter. It's a lot of work sometimes to get wood, but it's well worth it. I'll try to help with questions if you have any. I don't know near as much as some others on this forum, but I'll try.
