HP39GS Graphing Calculator
Buy new: $34.22 / Used from: $35.00

I purchased this for the symbolic capability. The manual is clean and the exercises work. It is easy to understand and a short time is required to learn each capability. The Manual impressed me. Many manuals are poorly written, not written for any audience, contain critical errors, in short, not really intended to be read.
