I am new here and own the good BUDGET player Yelo 800. I want to upgrade now though considering the poor picture quality on many disks the Yelo makes. I have found a place where I can purchase the Sony DVP-S735D, but this being almost two years old should I buy the DVP-NS700? I have heard the 700 was the replacement for the 735, and is relatively the same with better sound quality. I am mostly just wanting excellent sound and picture quality, being only 16 I don't have the money to throw around on exensive sound systems. Another thing, what is SACD?
