HHHmmm - freeview listings here
http://www.freeview.co.uk/channels/?__SITE=public&p[0]=channels
The choice is up to you of course, but if I could I'd probably go down the sky freesat route rather than freeview if I had to choose.
On the other hand I'd probably use a TV sender from the sky+ box so I could have the channels I'm already paying for, but if you've got family that's using it I guess that's not practical.

The thomson top up tv HDD recorder is only 89.97 from Asda. (160gb HDD) There are quite a few about now. (Just make sure you get one with two tuners
)
