The problem is, with the dual aranger's setup...you have to have room above the lower arranger to operate it....That's a deal breaker for me. The real cool features about the organs is that the upper is close to the lower AND overhangs in some cases, making a joy to play 2 manuals.
That's why I am looking to have the lower a simple MIDI unit, of the best quality I can find....worst case I could use a older used synth (Kurzweil, Yamaha or ??) and just use it as a MIDI kbd......I'm thinking that might work real nice.

Also, I do like Rikki's setup, and I could also have piano action on the lower??
Decisions, decisions....
