Help me pick a portable MP3 player...

[chesspain]

Given that I recently learned how to download music, I've decided to treat myself to an MP3 player. I already have a old, but still competent, home stereo system (i.e. Onkyo receiver, Techniques 5-disc changer, equalizer, 80 Watt speakers), so the MP3 player would most be mostly for when I take walks.

In choosing a player for me, the following are fairly salient issues/wants:

--FM receiver
--Compatibility with Realplayer10
--Ease of use
--Some type of display for song titles
--Price range of approx. $100 (+/- $25)
--Main storage for music will remain on desktop hard drive
--Durability

At this point, I am considering one of the IRiver 256mb/512mb units. I would like to hear from anyone with any IRiver experience, or with any recommendations for any other brands.
