Hey KAG, do like I did for my #1. Occasionally go out the the Auber site and see if they are on sale. A couple of weekends ago they ran a sale on them.
http://www.auberins.com/ For the #3 smoker you will need WSD-1500GPH also if you order from Auberins, you can get the permanent mount sensor for $2.00. I paid $178 for the pid on sale and $2 for the sensor. Just a thought and I know what you mean about laying out $200. But, after the fiasco I had with the Boston Butt a couple of Sat. ago. After Mass I ordered the Auber pid.
