Digital radios: Compare features & prices Roberts Sound 37 - CRD-37 review http://www.which.co.uk/technology/audio/reviews/digital-radios/roberts-sound-37---crd-37/review/
The Roberts Sound 37 - CRD-37 is a DAB/FM clock radio with the added bonus of a CD player that can also play MP3 and wma files saved on CD. The Sound 37 remembers the CD track you were last playing when you switched the radio to standby, so you can pick up again from where you left off. It also has 20 presets for storing your favourite stations, but does this feature filled bedside radio deliver great sound?
