I have an F1500. First winter the plate that the catalytic converter sits on warped and cracked my baffle. It was covered under warranty but took Regency and my technician 2 months to fix it (in the dead middle of winter). Worked for another season then the baffles started to crumble and need replaced again. For $4600CAD you wouldn't think this would be an issue. Getting tired of dealing with the cheap baffles so I either need to stock up or get rid of the stove. My priginal technician takes forever for warranty issues so I guess I'll just keep doing this out of pocket until I invest in a different stove. When it's working it runs great and is efficient. The airmate on top works but not sure it's worth the risk of having it break down in January. Unless Regency comes up with a better baffle material in the next year or 2 I'll definitely be getting a different stove. Also, I burn ash, maple, cherry and a bit of birch all around 10-20% moisture content (most around the 15%range).
