10K Glass Bead thermistor replacement

Hi,

I have been putting an RepRapPro Mendel kit together which I got a year ago but haven't had the opportunity to put together until now. Everything has gone fine until soldering the 10K Glass Bead thermistor up to the twin ribbon wire. I broke one of the wires off of the glass bead thermistor and now I'm not sure where I can get a replacement. Can anybody show me where I can get a suitable replacement?

For reference its the tiny thermistor in step 2 from this page on the wiki: [reprap.org]

Many thanks in advance!
