i think you should get a mobile with a mp3 player
otherwise just get creative zen. they're cheap and work well enough.
That's what I avoid as a rule. My mobile is only for communications, my MP3 player is only for music, my camera is simply a camera. I was looking at Creative's Zen, and its reviews appear positive.
How quickly do you need it? Because if you wait around a bit I'm sure one will come up on Woot and you can get it hella cheaper. There's constantly simple mp3 players on there, just check it for a bit if you aren't in a big hurry, and Woot tends to sell quality stuff so you're not gonna get some sharper image mp3 player that breaks two seconds in (my mom actually got one of these free with some thing she bought and I honestly did break it within 10 minutes of trying it out.
I've never been to this site, so I'll check this out.
A question: When connecting an MP3 device into speakers, does the basic audio jack provide optimum sound quality? I'm looking into buying some speakers that would play primarily from my MP3 player.
