I didn't find any replacement for the device but batteries are replaceable by any good tech.
I have an Iriver h10 20gc, but the battery is shot and I only get about 30 minutes of playtime on a single charge.
I like this mp3 player for a few reasons:
1. No software is required to add or remove music. It's as simple as dragging and dropping files in a flash drive.
2. It does not require id3 tags. I can goto an option called "browser" and it will show every folder and file on the device, instead of having to search by artist or by album. This is very important to me because I am a dj and the majority of my music is not id3 tagged, just basic mp3 files that I've named to my liking.
I would like to spend no more than $50 on a player, but maybe a little more if it does all of this.
Does anyone have any recommendations?
