Logitech Pure-Fi Express ipod/iphone dock, This is also a good device to charge your iphone before you go to bed and also use it as your alarm clock, which is much louder.
This deal was smoking hot a few months ago at £39.99 at play.com, Next cheapest is amazon at £39.99 also. It was reduced from £79.99.
Great reviews on play.com and amazon. If anyone has one of these a mini review would be great.
