3dee.at has them. I think reprap.me should also have them.
3dee.at is maybe the worst shop I ve ever ordered. Their support ends after receiving the money. They don't even answer your mails. We had problems with our witbox extruder, thanks to bq for their work and the exchange of it. Damn 3dee...
Actually I made several times exactly the opposite experience with their support as you. Ok, they do not read Emails it seems. But calling there always helps.
But I have also an advantage: I can anytime go and visit their shop :)
I bought three from Aliexpress, free shipping from china... can't insert a link, but you have to search for "thermistor m3"
