I went with the harmon markII. I bought it at the end of march and got to use it for a couple of weeks. I am real pleased with it and had no trouble really burning coal for the first time. I have picked up about 4 tons of pea coal from random people I have found on craigslist that were giving it away for nothing. All of the coal I have a bagged into 70 pound bags and have them stacked on four pallets. Its a lot of work but it is worth it I think, it saved me a few trips to Pa Im sure, and Im not paying the going rate for coal here on L.I. Cant wait for that first cold snap!
