You've got a couple of options, and in my opinion it's probably a decent idea to get one of each.
The first is the traditional stem themometer--there are digital and analog versions, but both are affordable. You'll need this for checking interior temperatures.
The second is a laser or infrared thermometer. These are great, but will only give you a surface temperature. I find them really handy in table tempering, for instance, to check the temp. of the marble or chocolate surface.
Hope that helps!
