Hi JerryM,
As far as synth`s last night I had a chance to play both the "Korg-Karma" and the "Yamaha -Motif 6" of the 2 ,I think the yamaha sounded better , but the korg had better "action". As far as arranger KB`s you could take a long time and think about the "Yamaha-PSR2000" (it`s still buggy, but a better buy than the 9000) Or wait until the "Technics-KN7000 is avalible (later this year) Best of luck with whatever you decide. O-BTW , Welcome to our corner of the web!!
