Sorry for the late reply.
The Leslie 122 is on the back burner, while I was saving my pennies to buy one I inherited an M2 from my teacher and got bit by the "i have to have a real hammond bug" and ended up buying a 1936 +/- hammond model A with a leslie 31h tall boy. My dinning room now looks like a small Hammond museum. The smell of old Hammond oil in the air is better that any room de-oderizer you can buy!
I love my XK3C and after making some changes to the settings it almost sounds identical to the A.
As for the Leslie for the XK, I will probably follow Jim Alfredson's advice and buy a Leslie 3300. I like the idea of it's size and portability and power
Regards.
