Yep, been digging around and trying to find some info on those keyboards. They look like Yamaha Electratone Stage A's. Can't really tell. If they are Stage A's, doesn't seem they are sold anymore, at least in the U.S. and even used they are ridiculously priced..used $7-10K, new $10-12K. Way above my pay grade, way above my talent! But I do love toys!
