Great info, thanks!! You guys have a wealth of wood burning knoweledge!! I have a felling I'm going to as well by the time I'm done beating this to DEATH! 
As for burn times, I think I'm fine with 10, 12 or 14 hours. That would be perfect for me, remembering that this will only be a suplimental heat source. In the dead of winter, I could start a fire in the morning, let it burn all day long, then reload in the evening and enjoy a nice fire show, then turn it down to low and let it slow burn overnighjt so I stil have hot coals to re-load onto the next morning. I just don't want to have to "start" a new fire twice a day....
Here is a quetion, if I buy an larger than required unit, will it burn more wood faster because it is bigger, even when I don't entirely fill it, and try to turn it down? Or can you really manage a bigger unit by not loading it with alot of wood....?

, this observation is interesting given all the discussion about the technical differences.
This made me laugh. Sounds familiar. One of the best pieces of advice I've seen on this forum is something like "get what she likes". I took it myself and it's pretty good advice at that.
