Can I evaluate ArcGIS Spatial Analyst?
A free evaluation CD with ArcView 8.x and the ArcGIS extensions, including ArcGIS Spatial Analyst, is currently available. Also, if you already have a license for an ArcGIS software product (ArcView, ArcEditor, and/or ArcInfo), you can instantly choose to evaluate ArcGIS Spatial Analyst when you run the ArcGIS setup.
