Looking for a cheap but decent thermometer. Have seen some of the digital ones with the probe and wire for 20 bucks or less but there are so many different options and things on them and they range from 15 to over 100 bucks I'm not really sure what to get. The ones with the wire you can leave in the meat the whole time right? You just run the wire out side of the smoker and hook it to the read out? Thanks for any help.
