Charles Edward Pax has announced that the T400 temperature datalogger is now being offered on Kickstarter!
The Pax Instruments T400 datalogger is an open source four-channel thermocouple temperature datalogger based on the Arduino™ Leonardo platform. It is ready to use out of the box with the features you want most. Measurements can be logged to MicoSD card, printed to serial port, and graphed. The T400 is a great tool for anything from live thermal process monitoring in the lab to long-term environmental data collection in the field.
This seems to be more accurate, though you have to provide your own arduino, screen, sd-card, etc:

That is not really an comparisan.
The one you linked to does: -40 – 125 deg C
The T400 does:
In theory a K-type thermocouple can measure temperatures from -260 °C to 1370 °C. The literature indicates a more realistic range is -200 °C to 1250 °C. The breakdown temperature of of the thermocouple sheathing will typically be your limiting factor. The thermocouples that ship with T400 are specified for a range of -50 °C to 260 °C.
