Charo look at this http://www.iceshanty.com/ice_fishing/index.php?topic=85267.0
I know you only mentioned cabin or hub shelters but have you given any thought to a one man flip-over? They come with a sled for a base so you can put all your gear in there and drag out the whole thing. Sets up and takes down in seconds.
I have the Shappell DX3000 and I have owned it for 10 years and love it. It folds up to a sled and has nice big windows and two flaps in the floor that you can open and jig thru. I do use a buddy heater in it and I set up to folding chairs in it. There are two things that I don't like about it and they are that there isn't really any way to anchor it unless you drill the anchors thru the floor and when there is snow on the ice it's like pulling a plow around. I usually drill a hole in the ice and use a home made toggle that i drop in the hole and pull up against the bottom of the ice and tie that to the pull rope and then set it up so the wind doesn't blow it away.
I have 2 of those folding chairs that you carry in a bag and I find they are just a little bit short. I'm 5' 9" tall and I can see out of the window but I have to lean forward on my chair to see out. I'm thinking about buying two of those folding director chairs.
