I just bought and installed the new 2007 Austroflamm Integra ll Pellet insert. The Austroflamm company (Rika) is now back to building them after a few years of having them built in the U.S. and the new stoves are great. Built like a Panzer tank and just as efficient. The only time they are a little noisy is when they periodically clean themselves during operation. Yep, these babies clean themselves. Wow, what a feature. They are definitely the Mercedes Benz of the pellet stove world.
