How much do you want to spend;and is it just a travel board?
Korg has the PS 60,about $600,lite,probably the easiest one to mix varied sounds but CHEESE keys!
The M 50;nice sounds,lite,has drum loops;CHEESE keys.
Depending on if you sell your MO;you could get an XS 6 or 7 for probably under 2 k.
If you leave your MO @ church,you could get the M3 rack-just move the rack back +forth,use a cheap controller @ home for practice.
I'm NOT liking the Kronos;basically KORG's top end board using the CX3 organ sound.Really? I've had my CX 3 since 2001-nice board -but I gotta question this.I played the 61 note @ GC and quality wise;think I'll pass.
Maybe look @ Kurzweil's PC line-a friend talks pretty higly
