Found a used Cookshack Model 009, mfg date 2005 listed in marketplace. Guy wanted $100 for it. Went and looked at it. He hadn't cleaned it forever. Had 3 layers of foil and grease in floor, rack rods were about 1/4 in diameter from baked on crud. He complained that he couldn't get it hot enough to cook his venison summer sausage. Plugged it in and it got warm, turned off and on with thermostat, door seemed to shut well, no rust, wheels would spin, cord was good. So I offered him $80 and he accepted.
Got it home, scraped out the inside, cleaned off the thermostat sensor really well, sprayed and soaked the side racks and grills with oven cleaner overnight, scraped the inside some more. Finally got all the grease and dirt and crud out. Reasoned the smoker with a couple of smokes using cherry wood. Cleaned the oven cleaner off the racks and grills. Ordered 2 new stainless grills because the old ones were down to the steel and copper, no nickel plating left after crud taken off.
Smoker seems to hold temp well even though empty when doing the re-seasoning. Some smoke leaks by door (but not too bad). Thermostat cycles within +/- 15 deg.
So I'm happy with my used find. Wish I could find a SM045 for same price.
