I saw one in april may at a local dealer that was having an open house. They added a contol sytem which tries to mimic the coal trol for one. They also added a hepa filter to the convection fan air inlet. However they cheapened up the feeded by putting a much lighter duty motor on it. That control sysytem is like the one I had on my p-61 pellet stove and looks and works just as crude with sloppy dials and knobs . They claim +/- 1 degree like the coal trol but I'll believe it when I see that . My coaltrol is always +/- 1 but that p-61 Harman with the same controller as this super magnum stove sure never was.
