Hi Uli --
Great minds think alike.
I've been tempted by the Neo Mini-Vent.
You've probably seen it -- the IK Multimedia T-Racks/Amplitude Leslie sim for iPad. Wish they had a limited trial edition. Even at $129 USD, that's a little too expensive to try on a lark.
Currently, I use a (sustain) pedal to control rotary speed on the MOX6 and Genos. With the Mini-Vent, I could ditch the sustain pedal and route the audio through the Mini-Vent. That would keep the space under my feet from getting too crowded.
Before spending money, tho', I need more experience with the Easy Sounds Organ Session expansion pack. The A100 registrations sound pretty decent for church-y stuff. The price was right, too.
Interesting comparison against the NE5. Yamaha still have a way to go. And then there's the matter of scanner vibrato/chorus...

P.S. Saw these Brian Auger registrations vs. the Classic Jimmy Smith:
83 8330 000 Perc: 2nd, fast, C3, no Leslie
88 8330 000 Perc: 2nd, fast, C3, no Leslie
