My intention is to use it for dance instruction. I would like to slow it down for teaching. But even for that +/- 5% is still a pretty big step. The discs I have now are NetMD creations (LP2 by default - I think) which are the ones I would like to use in this deck. The Tascam MD-CD1 aslo seems to have the same limitation (no speed control on LP2). I am also looking at the Sony MZ-B100 and the MZ-B10 for portable use. I have seen the B100 and like its speed control. But while I have not actually seen one, I am leaning toward the B10. I have never seen any minidiscs available locally, so I have to depend on what I have seen others use. Gary
