Was in Asda earlier and saw they have the Philips Streamium WAC3500D/05 Wireless Music Centre. It's got a big yellow and red stickers on it saying "£149.99 (£299.99 at Comet)", the shelf labels say £120.00 so I asked and it's now down to £120, it's still listed as £299.99 on the Philips website. The shop assistant told me Asda were selling them at a loss.
Looks a pretty good system, it has CD, an 80gig HD, an ipod dock, a front USB port which you can play music from and it supports wireless music transfer (not sure if that's only to other Philips devices...) and with the firmware update it also supports internet radio!
I'll link to the Philips website below which has all of the specs.
Only slight problem with the system is it only supports mp3's with a bit rate between 128k and 320k and WMA (but I can't remember the bit rates for that) so it wouldn't be suitable for those using lossless formats.
