K type thermocouple - Any suggestions?

Hi.

I'm looking for an option for the K type thermocouple that comes in multimeters because they usually give a lot of difference in temperature measurement.

I've seen some models on dealextreme:

There's even a cheaper one that supports 350ºC that would be enough for me:

Anyone used one of those? Can you recommend an alternative? My main objective is to monitor motherboard temperature during a reflow operation.
