I was able to find a replacement thermal cutoff (for my coffee maker) at Radio Shack, of all places.  Any good electronic components shop (even Fry's) should be able to sell you an SF-129E. 

Ahem, perhaps I'm wrong.  I just checked DigiKey; they have three TCOs with a 133C cutoff, but the biggest is only rated for 2A.  How do you know it needs to be 10A with that low a cutoff temperature?

I put "SF129E" into Google and got confirmation (thanks!).  Here's the datasheet from the first hit.

The closest DigiKey gets is a 141C 250V/10A cutoff from Cantherm.  Jameco doesn't seem to carry TCOs at all.
