Good tip Vaiva
Tupacs2legs is a good contact and will give honest opinions (I don't know her personally, but have read a lot of her postings here and elsewhere and she only speaks common sense and good practice)
It's a bit like contacting breeders in the other country, except that there aren't any trustworthy ones (that I know of) in the UK. I know of one 'breeder' who sells Pure
F3 CsV's in the UK...
