There's an Organ Stop Pizza near Phoenix. It's a shame that so many of the remaining magnificent instruments are relegated to pizza places, but at least they live. A place like the Tower Ballroom in Blackpool, England is now a glorious exception.
Understanding that this is a full pipe organ and thus a completely different animal, there's still no sound like a Mighty Wurlitzer.

speaking of different beasts, I attended the auction of Judge Hofhientz of Astrodome fame, collection of band and street organs. Wonderful instruments. I came and lusted in my heart, but left unsatisfied. I always wantedted my own private pipe organ.
