I purchased one of these woodstoves for the ice-shack last year. Well built and reasonably priced. The guy shipped it within 1 day of payment.
Note: I am in no way affiliated with this company, just wanted to share this with anyone who is looking for some heat. I spent a lot of time trying to find one of these last year, so thought I could save you all the time of searching.
I don't know how to insert a picture, but you can go to :
