I bought Sony's cheap and chearfull S350, and its got very nice picture quality, couldnt be happier to be honest, sound is great too. Simple to use, supports Profile 2 (memory stick required to save data)
It's also very green, using just a few watts while playing bluray's. a lot more power friendly than a PS3. Panny's model is good to, but most Panny players only have optical SP/DIF, I require Coaxial SP/DIF for my AV processor.
