Hello! and Ola

I am a Englishman, in Portugal
I have 2 Zon Powerboxes with card/Licenses.

I'd Like to View Zon on my MAC, and therefore am looking into USB DVB-S tuner boxes for a MAC.

Therefore I am looking at the Elgato EyeTV 310 with DVB-S and CI.

I'd need a CAM card too (right?) Which Cam Card? Conex? Access? Irdato?

Also anyone know a GOOD Sat shop in Aveiro? I want to replace one of the powerboxes with a humax or better!

Any help would be Great!,
