D3S ballasts options

Hello good people!
After successful installation of OEM bi-xenon headlights to my '09 Golf mk5, I'm planning to do same retro for my another car '12 Audi A3.

Audi are using headlights with D3S bulbs.
What ballasts are good for me? I don't know much about D3S bulbs and ballasts, so any advice will be much appreciated.

Thank you guys
