I don't work for sky...
Google my name, Tony Paulazzo or company, PED Computers. I'm a local computer engineer (for local people, natch), but if you do not yet have a dish or any type of box, and live in a Freeview-less area then check your options:
Freesat: £80 for SD installation (actually, I'm assuming you do get a box with this offer, but the Argos website doesn't actually say this); and for HD installation (which for now means four (4) hours of BBC programs in the evening and that's it), plus an extra £150 for the box... compared to:
Sky 'Pay once watch forever' includes:
SD box, dish install, 6 months free viewing of 'Entertainment Mixes, Variety Mix and Knowledge Mix, worth £102 at normal subscription prices', at a one off fee of £75 (with maybe a 10% discount code at Dixons - might be finished tho', was working yesterday 'sky10'), you have to ask yourself, which is the better deal - considering you can swap the box out at a later date.
