SD and MMC cards fit the same size slots(at least according to my 8-1 card reader), look around on ebay for a decent price.
I only paid around 40cad for the 128mb card to plug in my mp3 last year. The reader was found in staples for cheap a while ago(back when I got my digital camera and usb 1.1 was still big, hows that for a history lesson ).
as far as the drivers and software, it's usually easier to just use the card and a reader.
I have software for my mp3 player(classic mp6410) if I can get it working. had problems with it before I formatted my system a couple weeks ago, haven't tried to put it back in yet.

Why do people worry more if you argue with your voices than if you just talk with them? What about if you lose those arguements?
Slowly going crazy at work... they found a way to make the voices work too.
