After having a Skyplus box, I was worried that this would not be as good. Result, it's much better. For a start, the EPG is excellent, allowing you to search for upcoming movies for the following week, and to record them in advance (the Sky box doesn't so this, only searches on specific movie channels as opposed to all channels). It's got a great layout and easy to use system. The sky plus box has that annoying background music, this doesn't. It's a slick black box, which looks good, with a pleasing blue display. The initial set up is fast, straightforward and easy. The HD is excellent. Overall the image quality is superb combined with my Pioneer Plasma. I have used to manual set up to add a further 400 channels, most of which I'll never watch, but i really wanted to add fiver and fiver usa.
The only niggle is the remote, with it's tiny buttons. It means you'll find yourself squinting for the controls, as opposed to automatically pressing the correct buttons. Apart from that, I'd say it's a sound investment. The price seems to be dropping month by month. I paid £290 in April 09.
