Hi! I'm from Australia and am looking to buy a blu ray player to play American region blu rays bought on amazon. I do have a PS3 but I'm unaware as to how I would go about unlocking it to play all region blu rays. I was wondering if anyone could recommend a really good blu ray player for picture and sound quality- I don't need wifi or 3D or any if that- just need it to play blu rays really well. Thanks!
