Fran,
I agree with most of what you say but here in the U.K. home organs are still available from several manufacturers including Technics, Yamaha and Roland, but at around five times the price of our 7000 top of the range keyboards.
I don't know how they can justify this high cost because all you get is a larger piece of furniture, a pedal board two manuals, and perhaps bigger loudspeakers. The sounds, styles etc are no better or more extensive than what we get in our keyboards,

Love from Ogre
