Hanno,

Just like you I also have to look for a set of taps and dies for the CMP; I know some good quality ones do pop up on marktplaats.nl every once in a while; although usually not as a set, but as separate items, so you might have to keep and eye out to gather a whole set.
I have also seen good quality USED ones at the yearly KTR fair in Breda and at Baco in IJmuiden (only the smaller sizes though).
