A:I buy many of my price guides for under $4.00. Try Amazon.com and look for used books that are in your area of interest. Another good source would be estate sales, resale stores and community book sales. If you have a used bookstore near you they will put you on a want list. Antique stores will sell their used guides. They're also a very good place to put your name on their want list. I have always found that is handy to have a guide at my finger tips but since some of them very expensive I too will use my local library.
