Sadly, Jasper Sanfilippo has just passed away:

 I was fortunate enough to visit the collection twice (west of Chicago) but now it's by invitation only. Fortunately everything will be preserved by his foundation. Participants in the local engine show and an annual phonograph/music box show get invitations to tour his collection each year. He also has one of the world's best collections of mechanical music.
