Of course it might also be worth considering a PS3. Don't be put off by the fact that it is a console as it is also an excellent Blu-ray player, DVD upscaler, divx player and allround media streamer, internet browser.... oh and it also plays games!
When you consider the whole package, the PS3 is actually remarkably good value - especially as it is actually pretty accomplished in all those areas (it is far from being like the PS2 with it's fairly ropey DVD playback - the PS3 is one of the class leaders for Blu-ray).
