I have a 30" MES and I love the smoker but I didn't like the + or - 25 temp swing. So i ordered the following items from auber: Code: 1 x 25A SSR (RS1A40D25) = $15.001 x Universal 1/16 DIN PID Temperature Controller (SYL-2362) = $42.551 x K type thermocouple 4"probe, Smoker, Oven (TC-K3MM) = $11.95Cable Length Option 6 ft cable1 x Heat Sink for Solid State Relay, 25A (HS25) = $9.65 I also got a project enclosure 8x6x3" model 270-1809 from radio shack. I had to cut the holes for the PID and the switch with a dremel tool. Here are some pics and a schematic how I wired it. I'm still lacking the high temp wire but I did rig it to work. The first time I turned it on I didn't do an auto tune just to see where it was, and it way over shot my temp setting of 229. If I remember right it got up to 240ish. So I cooled it down a started the auto tune, after it was complete it will swing from 228 to 230. not bad. Not done yet still need to add a wiring harness so I can un plug it when not in use.
