The c series of Sansa players are pretty great. The native controls are easy to work with and navigate, there is a SD slot for expansion, the player is amall, and the battery lasts a long time. Add Rockbox, and the player gets even better. My player ended up being a dud. After a few months of use, the headphone jack stopped transmitting sound to the left ear. This is not normal, as I have owned a few other sansa players, and they have all been pretty durable, looks like I got a bad one.
