mp3 player

Now that I have another class to prepare for I think I know what I will doing on the majority of the plane ride to Kenya. Reading up on church history for starters. However, I am going to need some music to take with me. So, now is the time to venture into MP3 players. Anyone have any adivce on an MP3 player? I want one that easily downloads onto my computer--wireless would be nice if not too pricey--and I want one that will allow me to play songs in my car (FM tuner). What else do I need? And where do you find one for a good price?
