Hi -- Any recommendations for a good meat thermometer? I'm on my fourth probe thermometer (all Polder brand)...they seem to last for about 1 to 2 years then stop taking temperature accurately. I really like the fact that you can leave the probe in the meat, and just have it beep when the desired temperature is reached. Alternatively, I've considered a Thermapen...worth the money? Any other good ones to consider? Thanks so much!
