I'm looking to buy a cheap thermometer that I can use to monitor my temperature inside my smoker. I currently have a maverick - 2 probe but typically smoke multiple pieces of meat. My MES digital thermometer is not accurate at all - so I'm looking for a cheap option that I can use to monitor the temp inside my MES? It doesn't have to be wireless or anything. What would you recommend? I know that I could buy another Maverick ET -73 for $40, but was looking for other cheaper options, if possible.
