the goddam problem of small things

I went prowling the Internet in search of an mp3 player. My requirements are simple:

1. 1GB of flash memory or more
2. FM radio
3. Onboard usb plug (i.e. cable not required)
   
4. Built-in rechargeable battery

Not asking a lot, right? You'll be surprised, as I was, that such a player doesn't exist! Or at least I've not found it. The problem is that most player with onboard usb plug (such as the Creative MuVo TX FM) are usually small and slim like a thumb drive. And such small players tend to use AAA batteries, or so it seems.

Anyway, I've gotten a spare no-frills player from round head. So the case is adjourned indefinitely.

But if you're aware of one that meets the above, let me know!
