MP3 Player advice.

My trusty iRiver H100 has croaked. The joystick broke loose, and the
last ditch attempt to solder it back on fried something, and it won't
turn on now :(

So I thought I'd ask LJ for advice. My entire audio collection is
around 10G at the moment, so I don't need a huge (by today's
standards) player. I'm not fussed about video at all. I do however
listen to a lot of podcasts / audio books, and having the ability to
store several bookmarks is a big plus.As is mounting as a usb drive,
since I intend to download things at worked and the machine here is
tightly locked down, so I can't easily install stuff on it.

Research so far indicates the Sandisk Sansa range might be the way to
go. Anyone had one of these?

I was tempted to just stick the latest podcasts on my phone, but it
doesn't have a standard headophone socket, so I can't use my noise
cancelling headphone on the tube.

Any other recommendations?

p.s. appologies to anyone who had this as an email already.
