Portable MP3 players?

[Antti.Roppola at brs.gov.au]

Hi all,

Can anyone recommend any Linux friendly portable MP3[1] players?

I've seen a few USB ones that use things like compact flash
for storage and can be mounted as a vfat filesystem in Linux.
Some seem to be upgradable, so there's a chance they could be
used as ogg players, that'd be even nicer.

Anywhere in Canberra carry a decent range so I can do some
comparisions?
