Liza I have found that Thermaworks makers of the Thermapen has an oven thermometer - not sure how accurate it is at $4!
Just about every thing nowadays is of course made in China!
You will find it hidden under other dial thermometers on their site which focuses on their more sophisticated digital thermometers
Thermaworks is an excellent company to deal with - I have had 5 star service from them.
They shipped all my orders to Africa - no problem and it took less than 10 days!
Hector recommends the Dot 2 which I am sure is excellent. His advice has been most useful to me. Unfortunately I have been unable to order it offshore.
