Reasonably priced, simple thermometer/hygrometer
My physic teacher once said, you know exactly what temperature it is when you have one thermometer.  But when there are two, you're never sure.  The reason is because more often than not, the thermometers are a bit off from each other.  This is not the case with Mr. Misty.  I bought two and tested them for a week.  The hygrometer and thermometer readings are consistent on both units.  However, I did not test the accuracy of the readings.
