I can't comment on that particular stove, but that seems to be the most popular price point. If you can possibly stretch it to there, I think you'll be much happier in the long run. But look at everything else in that price range as there is a lot of competition there and a lot of great stoves. Pacific Energy's Super insert, for example, has a reputation for long burn times.Looks discontinued.. :/
I really like the Osburn 2000 insert. I think that would be the perfect fit, but the price is the only thing holding me back
