After smoking my first brisket the other day (see QView here), I could see why a remote thermometer could come in handy. When you open the door to check an IT, it sure drops the temp. and takes a little while to regulate again. After reading several posts here I see that many of you use a ET73 thermometer. I was just wondering what was special about that model that makes it so popular among you guys (and gals). I am open to suggestions as to what kind of thermometer to buy, but I'd like to keep it under $50 or so (if possible). And, if I can find one ad Target or Kohl's that would be even better since my wife and I have gift cards to each. Any help or suggestions you might have would be much appreciated.
