Hello! I'm looking for my first surround sound system. I really don't want to spend over 800.00 What do you think about the Cambridge SoundWorks MovieWorks II 5.1 or MovieWorks 408? I'm not looking for the best. Just something nice that will let me experience 5.1 dolby digital sound from dvd's. I don't want speakers so listen to cd's. Just dvd's. Any comments? Much Thanks!
