both of my old band keyboarders used Roland rs-70 which is quite nice keyboard for it price
as you see its light and not big very well to take and gig with it
default patches are also nice and it has enough options to create your own
we played from dream theater to heavy and gothic and at his free time our keyboarder even did some kick ass trance music (even though i hate this kind ) this keyboard didn't fail him with anything he needed it for
