I have an analog MES that I'd like to do some long smokes with but would prefer to not have to watch the smoker as closely as I do now. I'm using a TP-20 dual probes but as you know only indicates not adjust. After reading some of the threads regarding MES controller issues and looking over the cost of an all in one PID the choice looks to be either purchase a new MES with controller ($300-$400) or buy something like an Auber PID with probes for around $250 and upgrade my MES. I'm curious what any of you would choose to do and/or if anyone knows of a less expensive PID controller.
