The book press I use is one I ordered from Gaylord Library Supplies http://www.gaylord.com/
I would love to have one of the big, old-fashioned book presses, but in the meantime, am using this one. I'd definitely recommend it to anyone who is looking for a reasonably inexpensive (around $200) press. It's really sturdy, and also portable, so I can take it along when I do bookbinding demos. It comes with five pressing boards, and I have used it for books up to 7" x 9 1/2" .
