Euro-vox, advice needed please

[snake-hips]

Sorry if this shouldnt be in this section but wasnt sure where to ask.

I am just moving flat so havent even got a tv yet (working on it).

However thinking of getting one of these Euro-vox Max, but I have a few questions.

1, do I need any sky subscriptions?
2, do I need to have cable or will it just work off a normal aerial?
3, are any of the euro voxes better than others
4, can anyone recommend a good supplier who might show a technophobe like me how to use it?

anyone got one and can give me a bit of a review how they have found it?

Thanks for any help in advance.
