i was wondering which stove is a better bang for the buck. i currently have a us stove 5510, while it isnt terrible i want something better for the house. i would probably move the 5510 to the garage and buy the harmin or the englader for the house. the 5510 doesnt provide quite enough heat when it is extremely cold out. when it gets to the sub zero temps i need a few more btu's. what is your opinion on these two stoves?
