Now, does anyone know of any great deals for a compatible temp probe? The Sears one only goes to 500F, and is $30. Fry's online service has a very elemental Fluke one for $12, but it is not immersible and also limited to 500F. Cole-Parmer has a rugged full-range one for $22 I might go with, and a really nice one for $37. Both those are immersible.
