I'm not sure.
There are a lot of nice looking players to choose from, but this one caught my eye.
TEMPTATION MP4 MP3 Digital Player 2.4 inch TFT Touch Keypad 1 GB w/Rock Chip.
Unfortunately, it's only 1GB. Looks nice though. Micro SD card slot, plays AVI, and a built in speaker. 8)
The glacier battery is easy to replace from what I've heard. It takes Nokia cell phone batteries. Decent price too.
