Dreamer....As you know I have not played the SD1 but I have played the X1. I can say your comments apply to that keyboard also.
DonM....I have to tell you I like the PA80. The SD1 will have to "Knock Me Out" to make me change. Sometimes(if not always) too much "Choice" is not a good thing! How did you make out with the cable for the FC5 Ft.Sw.
