Polder makes a remote digital thermometer.
It has a probe for the meat that connects to the control box via a wire. you can measure internal temp, set a temperature alarm and it also has a timer. It costs about $25-$30.
Taylor has a whole line of thermometers, both digital and analog. They are mostly instant reads that are not left in the meat during cooking as the Polder is.
