Go with the pse740-it seems that Yamaha is a better standard, and supported device. I don't like the way Technics supports their equipment. You can even go to the Yamaha website right now and download the manual for the PSR740. Roland, Korg, Casio, Solton and Technics don't let you do that. Also, Yamaha has more sounds and lots of styles available for free over the internet. The Roland EM2000 does have a built in Zip drive but from what I have read from reviewers of it the EM2000 is difficult to operate compaired to the PSR740. I wish Roland had their Manuals online for download-but since they don't I bought a Yamaha.
