I also love sky plus.
We only pay #10 a month - we've got one sky plus box and one regular sky box. We only have their freeview package though - which they don't seem to advertise - we get the bbc channels, itv, channel 4 and a few other odd ones.
The recording facility is great especially as most things I ever want to watch are on after my bedtime. You can qlso pause any program to go and attend to two year olds who are supposed to be asleep.
