Thanks for the replies Wrinkles and Diki. I'm quite comfortable playing both the 700 and Genos, so I'll be looking for an external harmonizer. I don't care much about having the latest boards, only that what I do have works for me.

To that end, I still have and use a Motif ES from 2004 or so. It was the only upgrade I did from that series, after I sold my original Motif 6 to Nigel. I never upgraded again because the next generation boards did not allow me to install the 2 PLG synth-expansion boards I have in the ES.
