In terms of what is good or bad, that's what the people on here are for
My first post was along the lines of, "I can get these for speakers for £100, should I?"
You're right though about how stuff has been kept and any vendor worth their salt will let you listen to the speakers first.
IMO, I'd only spend around £100 or less on a Bluray Player. You can get some bargains on last years models of AVRs too such as
this from Richer Sounds. Add in some
speakers and there's a bit spare for some cables to connect it all together.
All of this would be upgradeable in future should you decide to go down that route.
