I haven't tried that one, but I do have this one:http://www.polderproducts.net/ProductDetail.asp?PID=150
I really like it for a non-remote thermometer. It is a dual temperature one too. The large bulb area at the end of the cable is for the chamber, and the probe itself is for the meat. It really does a good job in my opinion.
The drawback, if you plan on wrapping your meat with foil, you loose the chamber temp of the large bulb....
