IMO not worth upgrading a sky+ for skyHD - had a similar thread a few months ago ive had skyHD for 2 years now it cost me £300 to buy 24 months at an extra £10 subscription per month but i can only watch it through one telly to get the full effect - a telly we dont generally use - so its cost me about £500+ and probably watched less than 10 hours through it in the last 2 years - dont like wildlife programmes and watch football down the pub!!!!
