I am thinking of purchasing the US Stove Company's (King Pellet 5510). What are the opinions/reviews on this product. I would be purchasing it through TSC. If anyone has a comparable unit in mind that would be a better choice I would be open to it as well. Looking for at least 40,000 BTU's, priced between $1200-$2000, stand alone, same style as the King pellet (tall rectangular look).
