Right. If you're not bothered about HD channels then a sky sub is £18 per year Cheap box for sat only: Therefore, £38+18 and you're sorted for a year with all Sky channels, Pay per views etc. If you want a box that has a 7 day guide and some other fancy apps but Sky only then you'd be looking at one of these: http://www.zgemma.co.uk/single-sat-tuner For a cable sub you're looking at £80 per year. A dual box that has both tuners and you'd be looking at one of these: http://www.zgemma.co.uk/Sat-Cable-Terrestrial/zgemma-star-h2 You then have the choice of which sub to take. I personally have both, never really use the sat side but it's always there as a backup if the cable sub goes down for any reason. If anyone wants a link, I can point you to a reliable provider for both sat and cable. And TCIB, no these boxes aren't affected by forced box updates.
