Thanks, I will look at that one too. Like has been pointed out, my set up is ugly. but it is safe. double walled, insulated, stainless. =)The other reason to think about NOT putting a King in that space is access to controls. The bypass, fan rheostat and thermostat are all on the right hand side. The Princess would certainly provide great burn times, and it is not as wide. It is also a 6" flue. You may wish to make certain the pipe is in good shape and if it's single wall inside, consider double wall. The 25C Tax Credit will apply to qualifying stoves and help cover the costs of some upgrades to the chimney (if needed).
The others have already suggested several others options that might work as well.
