Vicks® ComfortFlex™ Digital Thermometer with Fever InSight. Love it. It is also a rectal one, but u can take the temperature from under the arm, and mouth as well. the best thing is that it gives the results digitally in 8 seconds and indicates a red light if the fever is high, orange if it is moderate, and green if it is good. It is about $15 if I remember. These are the features in a summary:
Faster readings; in as fast as eight seconds

Fever InSight large backlit display changes color to indicate temperature level.
Oral, rectal, or underarm use
