If you've got a massive 42" plasma, but you're still watching standard definition TV and DVD on it, then I'm sure you know you're not getting the most out of your technology. What you need is some kind of HD provider, but so far they've been rather prohibitively expensive. That's why I wanted to point out to you that Sky are extending their 50% off HD box offer. They haven't been shouting about enough - it's a good deal...
