Thank all of you for your responses! I've actually been looking at the MO8 for some time now, I didn't know a new one was coming out! I'd prefer a new one, and it'll ease the pastor's mind as well if it's new. Here's another problem:
I and the organist know how to use workstations and arrangers, and aren't afraid to learn a new interface, but my sister is lol! She doesn't like knobs, sliders, d-beams, etc. So I'm trying to find something that's easy to use as well, and not easy in the since that we think. Easy like yamaha dgx-100 easy lol. I'm leaning toward that MO, and I'll just teach her how to use it. Anyone have experience with the Korg m3?
Thanks again everyone for all of your help!
