i will recommend you to buy the Creative FM mu^2 which is integrated with FM radio and record function.
The capability varies from 1.5G to 4G because its storage is micro hard disk.
Another factor i recommend it to you is its wonderful sound quality.
and the price of it is more reaonable.
Last October, i bought an old version of mu^2 without the FM radio integrated with it which cost me 1450RMB. Resently i heared that the price of the new version may be below 1200RMB.
