My nephew has a Reading Lehigh, it throws a lot of heat. It's an automatic fed stoker stove. The only problem he has is it constantly needs to be adjusted for the weather. If you get one with a thermostat it will be better. The other problem he had was the powervent moter went bad and he had a hard time to find one. When he did get one it was around $200. This year was brutal for weather, and he had to go outside for about two hrs. to fix it. The powervent needs to be cleaned at least two times a winter.
Use you're own judgment, if you like it and the price is right go for it. Keep in mind a new one is around $2500-$2800 so make sure you get a good deal, sometimes a couple hundred more buys you new. Good luck.
