Don't overlook the Roland EA7. It has great styles, great sounds, great features.
It lacks vocal harmonizer, but the vocal sound is good. Good speakers, light weight . . .
Quite a bargain at the price point, and it IS the only arranger Roland currently has even close to a TOTL. The BK9 is out of production and difficult to find used.
I still prefer the Korg PA4X, but just barely.
