Current keyboard setup for Reunion band, Delaware

I have found more versatility for live performing with some of my cheapest/ lightest keyboards.
Yamaha p-66(with internal speakers)
Caseo for left hand, midied to korg m3 rack unit
Yamaha can record few songs for working out trumpet/ harmonica parts in whatever key the band want to play it.
The korg m3 unit has so many beautiful sampled classic/ vintage/ and other keyboards
No single unit weighs more than 30 lbs.
