So do you think that a total of 76 keys (on the Kurz) is sufficient to manage a dedicated Hammond area, strings, horns, or even a piano, and a lower level of keys sufficient to reproduce reasonable sounding bass? I would guess three zones on a 76 note board would be pushing it. The LH bass alone requires at least 15-20 notes in my experiences, and that leaves 55 or so notes to allocate to two other sounds--many of which should not have to be limited to only 2 octaves or so.
Seems a lot to ask a single keyboard to do, and frankly I've had song situations in which all three of those compartments need to be up and running and as accessible as moving my hand (i.e. to a 2nd board).
Finally there's the economics (always a consideration for us pro musicians!): I've been offered a brand new Mojo 61 for $1299 shipped from a retailer. Assuming you buy the desktop version of the GSI Gemini, the price I found for that online was at B3Guys, at $1199 retail. Is that correct, or is there somewhere else out there that this can be purchased for substantially less?
