Hello,
Sorry to break the trend, but for sounds and styles, The PA50 is the best bang for the buck. The OS is clumsy and complicated (I own one, and the KN7000), I am still learning it, but to my ears the 50 has` much better sounds and styles over the 3000.
Just my opinion, but I'll sacrafice simplicity for a much better sounding instrument even though the OS (on the 50/80)is difficult.
