I have gone through two of the normal type thermometers in the last three years. Very fragile and easy to break. Mercury is some bad stuff to mess with. I recently purchased the digital Thermometer and love it. Gives very quick readings, and you are less likely to break it.

Only down side it is a bit expensive. Hope that helps...
