I think I'm up to 25 machines, there was a 15-91 in a cabinet at a thrift store for $15, I would have jumped on it, but I have NO room for another cabinet, and the cabinet was a "modern" one, the next time I was at the same store, they had a decent enough shape cabinet, but also a modern design and they wanted $85, NO machine. I don't know how they figure out these prices.
