Oh I know about the prices and such, they are incredible, but I remember seeing a link somewhere that the company was advertising about 30-40 left, all at a reasonable price.
Right now there is one on amazon or alibris for about $75, and I know another place that has one for $115 (I am talking about the 1991 edition).
Also if anyone is interested, the 1912, 1915, and 1920 are all available in PDF format for free to download vis Google Books.
