A friend of mine told me about that manufacturer the day after I wrote this post.
They have many cable models, and good quality as far as I know.
Let's see if anyone has some more options.
I have ordered and bought cables from Reynolds Inductries, a company originally from Switzerland but having offices also in England and US. I think they have distribution for Huber&Suhner cables in much more attractive prices than the original H&S.
I bought test cables from them made by Storm (a US cable company).
Check them out and ask for pricing/availability at:
