I just got a Taylor weekend warrior digital thermo with probe. Its used for grilling. I tested it with water and against my other Taylor thermopen and lab thermo and it's pretty accurate. I cant wait to use it for real. They also have wireless ones.
I've got a ALLA DIGITAL THERMOMETER WITH PROBE had good luck with it! It's what my LHBS uses. It's not wireless but the cord is long and has taken alot of abuse from me.
