Audio Players for the Vision Impared?

Panz asks: "Over Easter my 86 year-old grandmother asked my parents to help her buy a CD player. Normally, there would just be a technology barrier to overcome. Unfortunately, my grandmother has macular degeneration which prevents her from using traditional consumer electronics. What, if any, low-vision friendly CD/MP3/audio players are available? Is there such a thing on the market?" What CD/MP3 players have interfaces suitable for people who have less-than-stellar eyesight? Features that would be nice to have would be backlit displays, and larger than normal text displays.
