Peter,

If the 'bay is your thing, go for item #110577237095. I bought a couple 
from this French seller and they are rev D which unlike rev E are 
supposed to work in the thunderbolt. That's because dallas/maxim changed 
protocols for high resolution temperature readings while the thunderbolt 
firmware was not updated. I haven't gotten around to do the mod yet but 
it should be simple enough.

The seller wrapped them in alu foil plus some foam and cardboard.

Good luck,
