what Hofzinser book? The two available in english are "Hofzinser's Card Conjuring" and "Magic of J.N. Hofzinser".
Both are quite difficult to get second hand. "Hofzinser's Card Conjuring" was reprinted by Dover, but they seem to ran out of copies. There are some first editions available for $700 and $1000 a piece. Check http://www.bookfinder.com/
Richard Hatch from H&R http://www.magicbookshop.com/
has a copy of the "Magic of JN Hofzinser" for $60.
Or you could get our ebook version of "Hofzinser's Card Conjuring" for an increadible low $2.50 (add $3.50 for p&h and $10 for a custom CD - you can put many ebooks on one CD).
We will also soon have the "Magic of JN Hofzinser" available as ebook.
