Just going back to the stoves for a minute - and the KP link - they guy who runs Windy Smithy, and who designed and makes the stoves that KP totally ripped off by the looks of it, "wishes they made a better job of them" as many people assume they're his stoves instead. He also says they can also be a tad sketchy on installation advice!
The originals can be purcahsed from Jon at
Windy Smithy
