I recently got a job where you can listen to personal audio while working, but you cannot use a mobile phone. Phones are banned and anyone caught using one will be given their marching orders. They have security everywhere to ensure this happens. ANyway, I have a 10 year old 20gb ipod which has seen better days and I'm barely lucky to get 7.5 hrs out of a charge. So I'm after a reasonably cheap mp3 player that has an expandable slot.
ANy recommendations. Something around the $100 mark would be good.
If you have a power source you could take your charger with you and then the battery life will not be an issue. Would be cheaper than buying a new one.
