I'm trying to buy my sister an mp3 player she can use for cardio coach. I don't want an expensive one... she will only use it for CC workouts. I saw ipod shuffle at Target for $49.99 and was going to get that but was told I don't want it because her workouts would always get shuffled around and she wouldn't know which one she was doing? Do I want one with a screen that tells what workout is playing? Do you know of any inexpensive ones? Any that you use for CC and like?
