A good dealer makes all the difference. I have a HeatMaster MF5000e and I highly recommend this model. I spent a lot of time researching the different brands of OWBs, the different types of steel, the simplicity of design and ease of use. I am not going to say that one brand is better than the other but I can tell you the reasons I chose a HeatMaster and they are:
1. Price
2. Dealer was local
3. Dealer was accessible (answered calls or quickly returned them)
4. Type of steel
5. Ease of use (Rocker Grates and Ash Pan)
6. Primary/Secondary draft control ( everyone loves to tweek! )
Those were my considerations. I really enjoyed watching the process of installation, mine was interesting living on a mountain with about a 70 degree slope with no road to the other side of my house where I wanted it placed (thats a cool story but I will stay on topic). Above all, my dealer completed the job quickly with professional work. I wanted to help him but probably got in the way more than I should, I just enjoyed watching it all come together. When you pull the trigger, I hope you enjoy the process as much as I did!
As far as scissorbill's comments are concerned, you have to weigh his comments with actual descriptions of his issues. I haven't seen him post any useful information that would help anyone come to any conclusion concerning his OWBs inoperability. I suspect operator error, frankly. The 'fire went out 66 times' - I have to ask a few questions... Were you trying to burn green wood? Or wet wood? Were the primary and secondary drafts closed when you thought they were in the open position? When it 'burned up', did you forget to close the door? I'm sorry, but if something doesn't make sense, then it probably isn't true.
I hope you find my insight useful.
Stay warm,
Michael
