I saw that and disregarded it. Price was too high and no fru-fru on it at all. There is a Magnum Countryside on CL for a lot less and the Magnum is very corn capable. Always on the lookout for another 6041 or 39 USSC in any condition (including deplorable) because I know them inside and out. There is one on CL but it has the old style 2 button board which is basically non user adjustable. I actually have a 2 button board in the shop that is fine. Mine came 2 button and I upgraded it to 4 button but the later models were 4 button and I have a lot of spare parts like combustion blowers and drive motors. When I replace a failed component, I always buy 2. That way I can replace the junk sleeve bearings with skate bearings.
My concern with any used unit is the same concern I have with buying used farm equipment. Usually, when a person puts anything up for sale, they don't take proper care of the item, IOW, let it go to hell.
Not tat I need a fixer upper, I don't but if I could find one for a reasonable price, I'd buy it and refurb it at my lesiure.
Despite all the hoopla on here extolling the virtues of a Harman, I one, think they are overpriced and two, I don't particularly like the fuel delivery system. I much prefer sticking to what I'm familiar with and my 6041 does a heck of a job heating the old farmhouse and has for years and with the 4 button board is extremely adjustable to suit variations in fuel.
If rice coal was available here, I'd have a Keystoker in a minute. Hard to beat a coal stove. I could order rice coal from Blashak but I'd need to buy a couple ton at a crack and pay shipping on it so that's out.
