Thermocouple for high tempertatures

Hey, I am planning to build an arduino controlled kiln, and need a thermocouple to sense the temperature. Find lots of K-type thermocouples on ebay, however, the temperature rating are too low.

Anyone knows where to get an inexpensive thermocouple that can be used on temps up to 1600C (2900F)?

Define inexpensive. http://www.nanmac.com/handbook/a11.html

If you really want to go up to 1600°C you can't use thermocouples type K. You can have a look here http://www.omega.com/section/thermocouples.html. The prices are usually ok and if you tell them your application they will recommend a suitable product.
