Thanks for your advice.
It made me think about it again and I decided to spoil myself and bought and Iriver iHp120.
It's got a 20Gb disk, an Fm radio and a voice recorder, and is connected to the pc over usb 2.0
Downside is that it came with a leather cover
This leather cover was in the box, not on the display and it wasn't mentioned on the website or the reviews
