I don't have the time to build me a new patio offset and was looking at the Oklahoma Joe's Longhorn. My question is the Char Boil Longhorn that Lowe's sells the same thing or a knock off? If it is a knock off are the just as good or should I find the Okie Joe? What stores stock the Okie Joe? I would like to see the smoker I would be buying to inspect doors, welds, etc.
