"I know that Kurzweil has good piano sounds, but does it have good electric pianos and good organs as well??"
Well...they are all right, but aren't most of you guys playing in a church where there is a B3?
I think people need to be real familiar with a B3 before they start trying to find keyboards that simulate them.
If you want electric pianos and b3, then I would go for the Nord Electro. It has good drawbar simualtion and good elec piano sounds, along with effects, and it's all right on top of the board, you don't have to go into any complicated small screen menus to access them.
I believe that from the Kurz 2700 onto the most recent has drawbars for the Hammond sound.
