Help required sound system for a panasonic TH37px70

[Mikefst]

I am setting up a new system, old telly died,VHS and midi system made by Noah when he was waiting for the water to go down.
I will probably get the Panasonic TH37PX70 or the 2008 version if they have one, plus the DMREX77 hard drive DVD recorder,we don't watch a lot of DVD' so top movie sound is not a major concern. No sky only freeview
What sound system should i get?
I need good tv sound, good music playback and to be able to connect to the pc and download direct from i-tunes ect.
The Panasonic SCPTX7 home entertainment centre sounds good on paper,especially if the Viera link works, but reports are inconsistant,and its expensive, any other suggestions at £300-£500
Many thanks in advance
Mike
