Hey all, I am looking at a new pit boss pellet smoker. I want one in the 800 series. As of today 12/15/2021 I believe most of them have the new PID controller. What is the difference in the Navigator $899, Pro Series II $549, Sportsman $699, Mahogany $599, Laredo $450. I have read all I can and the price swing between the Navigator and Pro Series seems to high for there not to be a major difference. Help Please!!!
