Non Elect Pellet Stove

Went to tractor supply last night to watch a demonstration on a non electric pellet stove, it's build by united states stove company. It's 40,000 btu and is supposed to heat up to 2000 sq. ft.. I was impressed with the amount of heat it throws, but it has its drawbacks. They offered 15% off if you ordered one. The drawbacks are:

1. It requires a flue versus direct vent

2. Wood pellets are $250.00 a ton.

Here's a link of the pellet stove I saw:
