The most insane keyboard collection I'd ever seen belonged to Richard 'Aphex Twin' James. He had a whole building that was rammed to the gills with esoteric synthesisiers. He even had the famed VCS8 and the behemoth Yamaha GX1. So few were made you can trace each one back to a 70s super group (his being Hot Chocolate’s).
