If you are not lucky by getting your stuff from private, try these companies...both are very relaible and ship very fast. Since you are from the EU, you can buy from them without VAT (in case you have a valid VAT registration number)
Yes kopterworx is my favourite dealer, and i think that's the way i have to go. I just look first if i can find used bare frame to supersize my current cinestar 6 with CS gimbal to CS8. So i can possibly try to do Y6 setup from my CS6.
