Sure, MP3 Players are a dime a dozen (in variety, not price).  And sure, they usually have the same features such as loading tunes via USB, the FM Tuner, and small ones usually hold about 2GB worth of memory. 

In fact, the only thing that makes the Haier America Trainer stand out is the fact that it has a built-in clip, a heart-rate monitor, a pedometer, plus a stop watch.  So for those who are interested in taking tunes with their workout, you might want to give this one a try.  It is available now for a price range of about $55-65.
