What is the best temporal thermometer

I'm a home health nurse in need of a sturdy, accurate temporal thermometer. Any suggestions?
I like the temporal one you can get at WalMart. Works great!

I like this one. It's pretty much instant and non-contact. The accuracy is the same as the tympanic thermometers.http://www.clinicalguard.com/swine-f...ter-p-190.html
