I picked up a Hyundai MP3 player the last time I was in Hong Kong. It has 256MB of internal memory, but also has a slot for SD memory cards. This was the main reason I bought the player, as none of the other players on display at the electronic market had the expansion feature. I have a 1GB SD card in there now and am happy with the amount of music it holds.

The major drawback is power consumption. It uses a single AAA battery, and will last about 5 or 6 hours on an alkaline battery. When using a rechargable battery, that time is reduced to 2 to 3 hours, due to the discharge curve of the rechargables.

As for WMA and DRM, I'm personally not impressed, not because of the copyright protection, but for the rigidity of the format in it's current stage. Even when running on the same PC, I've had problems with players not recognizing it after moving the file from one directory or another, or in one case, after a system restore.
