Try the Sony CD Walkman D-NE900. You can shut it off and resume playing in the middle of a long mp3. You do have to burn the mp3s to CDs first. It can go up to 75 hrs on a charge with the battery and the backup combined.
I?m still looking for a flash mp3 player that won?t send me back to the beginning of a 45 minute file when it times out on pause and shuts off to save my battery.
There are some hard-drive based models out there I like but the propriety unremovable battery replacement will sting pretty hard when the battery retains less and less of a charge. I would buy an Ipod if that weren?t the case. Also when the charge runs out, I like to be able to pop in a fresh charged battery right away and keep listening.
The Cnet mp3 buyers guide link has some helpful info as well
I love music but mostly listen to Audio Books and selfhelp-type CDs.
What's the Best "Overall" MP3 player for listening to & transfering tapes & CDs?
