The Korg PA-80 is an arranger with a watered down Triton engine. I recommend you check out all the alternatives before investing in a high-end keyboard.
General Music SK760, SK880
General Music WK8SE
Korg i30 (out of production)
Korg PA-80
Korg Carma (Rumored, not sure what it is)
Roland VA-7
Roland VA-9 (Rumored for March announcement)
Solton X1
Solton SD1 (available in a few months)
Technics KN-6000
Technics KN-6500 (to be announced)
Yamaha PSR9000
Yamaha 9000Pro
Each of these keyboards has its unique strengths and adherents.
I just got hit by the rolling blackout in California and am on my UPS so I will get off.
