Let's not get the water poured on us by TSB, even though I want to thank him for noticing some of my points, Hey they don't call me Curious George for nothing !
Anyway, Aside from the other factors that I pointed out earlier to consider ( looks, efficiency, etc ) few other things come to mind as well:
Weight and size of the stove is always something to be considered, I always liked the Alaska, because I can always manage to move it anywhere all by myself, you can easily dissassemble the Alaska, or the Reading by removing the doors, and take out the rest piece by piece, once that is done, you can manage to move the shell without any difficulty, I just transported one last week in a small minivan, without any help, it's hard to do that with the Harmans, or the Keystokers. For the Warmer weather season, I always take mine out of the house including going up and down steps, all by myself.
Other Menmbers posted about Leisure line having the best customer service, and I don't doubt they do, I believe all manufacturers have great service, they keep each other in check. I have dealt personally with the Reading Stove Company, Alaska, and a Local Harman dealer in the area, I can not complain about any of them.
The one major thing to consider, is the cost, if you can pick up a stove from a couple going through divorce, for real cheap, then all other factors are null !
If I think of anything else , I'll let you know.
