I have and love my C&W Chip Price Guide, except for the binding - the book won't stay open without crushing down on the binding. So, I took my book to PIP Printing (I've been told you can get the same thing done at Kinko's) and for $8, they installed the binder shown in the pictures. They did it while I waited - about 10 minutes.

Now the book stays open flat at any page. You will love it!

C&W - you should consider this kind of binder on your next release (JMHO)
