D-Link DMP-100 MP3 Player Review by The Tech Zone: "The only thing I dislike about the DMP-100 is that the unit only has 32 megs of memory. That means I run out of songs during my 1.5 to 2 hour workouts and have to repeat some. Yes you can expand the memory of the unit using SmartMedia cards. I added a 32 meg SmartMedia card to the unit and that extended my musical enjoyment. However, SmartMedia is very expensive. A 32 Meg card will set you back $80."
