I have a digital one from Lullaby conceptions as well.
The biggest advantage of the digital ones is that they are easy to read, you can take your temp when you are half asleep and once it beeps turn it off. When you wake up later just press the button to see what your temp was to record it. Great for weekends when you're trying to sleep in but have to take your temp at the same time as during the week.
Also definitely go for the 2 decimal places.
