Finally joined but have been using this forum for some time for information. I have been smoking for 5 years, started out with a WSM and progressed. I now have a Weber performer, a Green Mountain Pellet cooker, Weber smokey Mountain, a Oklahoma Joe offset, and a gasser. Got rid of my electric smoker from Smokinit, just didn't do it for me. I just bought the Ok. Joe and want to do the mods, basket, tuner plate/diffuser, seals etc... Has anyone purchased the diffuser plate from Horizon for the Ok. Joe?? If so does it work?? I really wanted to buy a Lang reverse flow, could afford the cost but when you add the shipping at $550.00 it put it over my budget.
