Samsung
The Bottom Line: If you're looking for a small, practical MP3 player to throw in your gym bag, the Samsung U5 is great option that won't break the bank.
All the Samsungs I've had were great player for the money. Most have tons of features. I recommend the P2 model for it's ipod beating features and price.
Samsung make 3 current MP3 players: The U5, R1J, and R0. The U5 has no screen and is similar to the iPod shuffle, while the other two have excellent screens.
My aunt purchased one of these not too long ago. They work very well and are very easy to work in terms of loading songs onto it. They are also affordable.
