carpneils - thanks, it makes sense. But... Considering that we won't be relying on it for heat (i.e. we can let it die if it gets too hot), and considering that we won't be using it that much (so the waste wouldn't be as much of a concern as it might be otherwise) and considering that we can use the screen, or open the attic trap door (or window) to let some heat escape, and considering that we REALLY would like a big window to look at the fire through, am I totally crazy to get the bigger one? We already put the money for it in the allowance with the contractor... Do I sound like I really want the 44, or what? MSG - The Yikes part was for me, like 'yikes, did I make myself look foolish AGAIN??'
