Then there's always the Superfast Splashproof Thermapen...
which comes calibrated to NIST standards including a certificate of compliance.
I like the idea of the Thermapen and I like that its calibrated. It does seem like it could be a good everyday tool. It is expensive though.
This still doesn't alleviate the problems inherent with any electrical or mechanical device...they can go out of calibration. That's why I like the security of that old fashion mercury in glass thermometer for calibration checking. The only way its going to go out of calibration is for it to be broken and then you have a whole lot more problems. My NIST thermometer only comes out for calibration and is never used for real work. Of course, that old fashion thermometer has to be calibrated to an NIST standard for it to be worth anything.
