I didn't think this would get much attention in the audio/video sources forum, so I'm posting it here. Admins, feel free to move it if you like. I'm thinking of getting a portable mp3 player to listen to while I work out (weightlifting, running, biking, etc.). I would like something (relatively) small and light, so I'm not too interested in jukebox-style players. I really don't want to spend a whole lot of money on it (under or around $100 if possible). I usually only work out for an hour, max, but I want to get something that can hold slightly more data, because my car CD player has a line-in jack I could use with it. I think I might like a 128 MB model, but a 64 MB model might be okay, too. Can someone explain how the storage capacity translates to time? Is it dependent on the bitrate of the mp3? One model that has caught my eye is the Rio 800 - I can get one from eBay for around $90 with all the accessories, but the only ones I've seen are factory refurbished units. Is there any reason why I shouldn't buy one of these? Are they reliable? Does anyone have any recommendations? If you own an mp3 player that might fit what I'm looking for, what kind do you have and how do you like it? Thanks for your help, everyone. Oh, one more thing, if you listen to music while working out, what kind of headphones do you use?
