This is the reason they are discouraged here. Unsafe, inefficient, not EPA approved, will never heat much more than a room. and dangerous as all hell. Note the white haze on the shell, sure sign of overfiring, which is basically what you have to do to get good heat from these stoves. The person's claim to paying "over $500.00 new" is a complete line of pure grade a bullshat. You can have this stove new for practically what he is asking for it. He found out the hard way and is trying to pass it along to another sucker. So many ill informed will actually consider this stove.
