TV Card Help

I need a TV card for my media centre PC (HD would be a bonus) but cant seem to find a decent one.

The trouble I have is that I live in an area that can't get freeview and I dont even have an outside aerial, what I do have though is sky with two LNB feeds so the card will need to accept that source and not a standard aerial connection.

I've looked around and the WinTV-NOVA-S Plus or the WinTV-NOVA-HD-2 for the HD option.

Does anyone have first hand experiance with these cards and advice would be greatly appreciated.

Cheers
