These ones are brand new and seem to be discontinued stock. Amazon US and ebay have them for over double the price. During my research I came across cheaper thermometers online, but these claim an accuracy of ±0.4°C over the range of -49.9 to 199.9°C, thereafter ±1°C.

Also available in Tan colour for the same price.
This is my favorite digital thermometer. My only wish is they made a version with a button on the outside to change between Celsius and Fahrenheit so I didn't have to keep googling it or consulting my chart. The Version 4 has a backlight which is nice and uses a AAA but more expensive. This version is more than good enough though!
