Well, go look at the Before the Osburn post in the Pictures forum...You'll see mine. My sister has a Lopi Answer insert. Lives near Seattle, so I don't see her much. Anyway she spent a week here in Dec. and was seriously impressed with the Osburn 1800i I have. The Osburn handles much larger logs than an Answer, probably not as big as a Revere, but a Revere and a 2200i are same firebox size. The Osburn has a view of the fire that blows the Answer away, BUT, the glass does get a little build up on it that needs cleaning once a week or so, super if cleaned every other day. Blower included is great. The stove is build very solid. From the unexperienced eye, it looks every bit as solid as the Answer. No secondary bypass, so if a fresh log end is very near the glass door and you open it, some smoke will get pushed into the room for a second or so, but then gets sucked back in.
Burn time is a solid 8 hours with Oak or Elm if really stuffed. The fire in the Osburn is very easy to control but with a really full firebox it really gets roaring for about 1/2 hour then calms down to a controllable burn after. So would I buy one again? Yes. In my lower level I'm looking at a cast stove, but if I do change my mind and go with a steel stove the 1600 is likely my choice.
