I currently still plug myself into a cassette player and make my own running tapes. Are there any others out there still doing this? I want to get more up to date and download music from my computer. Given I am fifty and not up to date with technology what would be best to buy. I don't understand the difference between an mp3 player and an ipod. What I buy must be under a 100 pounds and stable while running. Would be glad of any suggestions from others who enjoy running to their favourite music.
