I looked for years and only found the typical US $300 price-range. If you look on bookfinder.com, there are even places in the US selling it for 670 EUROS!!! that is insane.
This means that all one has to do is set oneself a range, and look periodically. I hope someone snatches this one up. As for me, I've still about 80 euros earmarked for tarot/playing card/game books, and I'm being stingy with it.
Before Christmas, Michael noted a copy of Moakley for sale, and when I looked I found almost every copy was reasonably priced, and, as I had some money, I began a spending spree on long-sought-after books... the last installment being a couple of weeks ago, after about 20 books.
There is nothing left in my price-range (Patch, some odd reprints from the 16th century, Hind, etc. being just out of my reach), but I keep an eye out.
