One of our site sponsors has Showtime offer for 595 Euro. Check for details about which channels it will open as there are few options or ask if you can add more channels.

If this is too expensive, try contacting satworld.gr in Greece.
They don't give prices in the website so you need to contact them by e-mail or make a telephone call (might be better as they have never replied to my e-mail messages).
