A couple things to consider. I have a cabin on Schroon Lake that may have some of the issues that you will.
Will you be keeping the cabin warm all the time? Are you looking to heat the entire cabin? Taking even a small room (in an unisulated or close to it cabin) from around 10 degrees up to 50's to 60's isn't easy to do without an oversized stove in a reasonable amount of time. If you are talking about lake effect, do you have to deal with wind off a lake which makes it even harder? For example, in my cabin, I have a 12x16 foot front room. It's the only room I heat in the winter. I've used 30,000 btu to HOLD a mid 50s temp due to wind. This is an insane amount of heat for such a small room, but it is what is required. Drop the wind and I only need half the heat to hold the temp much higher.
The Jotul combis are big cast iron stoves. They will hold heat well, but steel will radiate heat faster. Something to think about if coming into a cold cabin. Maybe you are comfortable lighting it then going out onto the ice to drill holes for fishing. The cabin will still be cold when you get back.
I think you might want to consider a newer stove due to space and fuel requirements. An older stove will require 3 feet clearance on the back and sides. When you map out the amount of space you loose with that, it's quite a bit. Newer stoves have lower clearance to combustibles. You can set the stove closer to the wall or furniture closer to the sides. As for fuel requirements, higher efficiency stoves use less fuel. Physically getting the temp up to a livable level will be faster and require less wood, which means less wood storage, etc.
HTH,
