I just ordered 2 Taylor Digital thermometers from amazon .I have found that they are fairly accurate, before the Taylors I had 2 Pyrexs that I got at Wally World they didn't work that good! The Taylors with shipping and handling $ 26.15
jrrollins - Taylor makes a very good thermometer as does Oregon Scientific. There are many brands to choose from - sometimes there's no substitute for quality. I personally have a digital instant read hand held thermometer along with two of the "wired" thermometers. One has a remote unit so I can see the temps while doing other things. It is the Oregon Scientific. Wally's has thermometers but may not be the best but will work... just check them in boiling water or ice water to verify temp readings

the best bang for the buck is the Maveric Redi*temp. it is wired (digital) and with a remote sensor. this unit has two, count them two heat sencing probes. one to monitor the temp of your food, see how fast or SLOW your food is cooking. the second probe is for constent control of your smoking chamber. yes that is right, one probe for the food and one for the smoker chamber. it is never fun to check on your smoker and discover you are in a heat spike!!!!
they run around 40 bucks or so. i have had mine for over two year and many times forgot it on the smoker and left it in the rain and it still works fine.
