Hi, I posted about fireplace inserts back in August. It's a little easier to find out about tractors than stoves! Anyway, I ordered a Lopi Freedom insert yesterday. I had narrowed it down to the Avalon Olympic 1190, the Lopi and a Quadrafire 3100-i. I disqualified anything with a catalyst. My wife preferred the styling of the Avalon (as did I) since it is available in a black door. But out of the three, the Lopi had the heaviest door and thicker gasket. I also didn't like the firebrick in the Quadrafire (looked pumice based). Another concern was the ability to flush mount the unit. the Lopi can be installed relatively flush, 1-5/8" sticks out, or extended. The Avalon and Quad both stuck out over 6". Also, I ordered a "full liner" instead of the "direct-connect" kit that is available. My primary reason for this is the ease of cleaning. To clean a direct connect would require the insert to be slid out.
Any of these stoves should last a long time. Just like a Kubota, Deere, NH.
