would you happend to know were to find one?

Just bought myself a brand new Dreambox 7025S,

Box type: DM7025S (dual tuner)
GUI (enigma1/enigma2): factory default
Firmware version: newest factory default

I've got a Canal Digital card(bought a package with parabol, tuner included), and are planning on getting a Viasat card too.
I don't know anyone to share cards with so...
My question then is what image should I use to be able to use both a Canal Digital card and a Viasat card in the Dreambox7025S tuner, and were's to find them?

Help is much appreciated!
