Thank you!

Another option is Zubal Books. (http://www.zubalbooks.com) They have a very large collection of antiquarian technical books. I just searched them and they have a copy of HP-48G/GX INVESTIGATIONS in MATHEMATICS. They are a little pricey; however, they are very accurate in their description of quality.

I have bought several old books from them and have always been completely satisfied.

Disclosure: I have no monetary interest in Zubal Books. Merely a satisfied customer.
