hello... would someone be able to advise me before I buy the Panny PWD7 ? I see a lot of PWD7's advertised but they have different letters towards the end of them .. are these different models / specs ? Also for my usage what board should i buy with it ? - I will be using SKY+ only for tv, and DVD with DVI/HDMI outputs - oh and Ps2 (3 when it comes out). Not bothered about HDTV for now - six channels is not enough for me at the mo. anyone advise on the serial numbers and which board / connections I need ? thank you very much.
