Thanks for the helpful replies everyone. Has anyone used the SanDisk Sansa
Clip? Supposedly it works out of the box with at least ubuntu (though I'm
running CentOS 4.6) as long as it has the most recent firmware. There have
been some excellent suggestions but my budget is extremely tight - the $50
for the Sansa Clip is just about at its top.
Mmmm... grad student pay....
