Buy a "modded" cable box.
Get the basic subscription.
Buy a card programmer and a flash card.
Put the supplied box in your bedroom.
Download latest hex files and program new card.
Watch every available channel on the modded box and run the feed to the normal box (not skyone).
Alternatively if you know a cable fitter get him to turn on your feed for a drink (don't need a subscription).
Done, 4 years of free cable.
chipped digital sky box ftw, runs off standard ntl/telewest/virgin cable, all 1000 channels, ship
