Jeff, I haven't used those, but I have 5 of the Lopi Berkshire stoves, and they have been incredible over the years. When we built our log vacation home up in Fairplay we decided to put 1 in the finished basement and 1 on the main floor. This home is at 11,000 ft. and it gets a wee bit chilly up there in the winter. We have no central heating, and these little guys will blow you out of there. Up there, of course, they are propane, but in our primary home we just put 2 new nat. gas ones into our 1200 sf addition, 1 on each floor. One of those floors is my shop, and I couldn't be happier with it. We also have a gas insert in our family home we've had for 11 years without a hiccup.
They have served us well for a lot of years now, they're incredibly efficient a have the added bonus of providing heat even when there is no power to the house, a real plus at the foor of the Continental Divide in winter where the power often goes out! I did not want the mess or danger of wood fires up there, wanted to turn it on when we get there and off when we leave, and set it to 45 when we leave so the pipes won't freeze. Can't do that with wood...
Hope that helps,
Dale
