Buying a new keyboard

[Eprivirus]

I currently own the Korg i3 workstation which is still a great piece of technology, but its old and does not have the new styles I want.

Can anyone recommend me any Keyboards/ Arranger? I prefer live performance. I was looking into the Yamaha MOX 6, but unfortunately its not an arranger.

Other keyboards that I have looked at

KORG PA500
KORG PA50
YAMAHA PSR S710
YAMAHA DGX-530 / YPG-535

My budget is around $800 - $1200 USD.

Thanks for your recommendations.
