I discovered a wonderful sefer on the Otzar HaChachma program (and on Hebrew Books here http://www.hebrewbooks.org/15241) and can't find a copy of it in any bookstore. It's called אמרות טהרות and is on Bava Metziah. The last printing of the book seems to have been in the 60's.
Where can I get this book? I live in Israel, so if anyone knows of a place here to look that would be the best.
[I do not want to order a copy made from the PDF on HebrewBooks since, as the comment shows on the HebrewBooks page, that version is missing many pages.]
