Hi
I'm a theatre organ nut and thought I would commnet. The street organs you are describing probably do not have a decent equivalant sound in most modern arrangers. I've had many keyboards & organs over the years and right now my best guess is that the KN7000 technics is the closest you will get for your particular sond. The organs are very good and plentifull I aslo will add that the theate organ in the KN7000 are excellent. See if there is a dealer near youto try one out.
