Resolved Question: What good sports mp3 players are there out there?

I have had my Sony Walkman NW-S203F mp3 player for over 2 years now and as things do, it is starting to die.

The battery is always dying quick and it doesn't charge the way it used to. I am not going to go to Sony as I don't want it to be sent away. This is how it looks like - http://www.martinrothonline.com/personalhealthmonitor/Reviews/Sony%20Network%20Walkman.jpg

It's very easy to use and has a band which put on on your upper arm. You also flick the switch to change the songs. I guess you could say it is my best friend in the gym.

Sony do not make this one anymore. eBay does not have it. So I have to face the fact of buying a different one. But what good ones are there out there? I don't want an iPod. No colour screens as I have had trouble in the past with them and I only use the mp3 player for music, that is it. I need it to have an arm band, easy to use and good quality. Thanks in advance :)
