Due to several circumstances, I haven't tried the Nord C1, but I have tried the Hammond XK1 which has the same rotary simulation as the XK3c.

The XK1 has a very accurate sim in my opinion...closest you'll get without the actually "moving air" of a real Leslie.

It's less expensive than the XK3c and has a different keybed, but it sounds pretty well identical to my ears.
