iPlayers.

As I've mentioned before I'm not friendly with new technology and any posting on here is about the limit of my capabilities. Thing is, that as I can't read too well these days I have taken to listening to audio books. According to my daughter I should get something called an iPlayer to replace my ancient walkman as it is much cheaper to 'download' audio stuff as compared to buying second hand tapes off Amazon and e-bay. So, any recommendations for a decent, easy to use instrument that would do the job? Thanks.
