BBCHD free (more or less)
You dont need a Sky HD Box for BBC HDef - you just need a sat box that will decode the HD broadcast.
I use a PACE DS810 XE - plug it in like your sky box and youll get the FTA sky channels and the BBC HD channel too.
80 quid on ebay - no subscription - though its not a PVR. But its worth the sports events, the top end shows - and gives you a chance to assess what you will be missing if Ofcom dont provide bwidth for HD to all of us who pay our licence fees. Flicking from the FA cup in HD to SD is shocking.
We dont need HD - like we didnt need colour - like we didnt need live broadcast - like we didnt need ... total arse.
