I own the Psr-S900, which I like the Styles very much but key-feel and vocal-harmonizer don't suit me. A music store offered me a good deal trading my Psr-S900 for the Roland e-80 adding some cash on top of that. The problem is, since it's an on-line store located in another state, I can't test the e-80 in person.I know it's supposed to have a better vocalizer and key-feel. My main concern are the styles.Those of you who own or played the e-80 could give some comparisons between the S900 and e-80? Any comments are well appreciated. Thanks, Telmo.
