ArcGIS For Home Use - in November of 2011, we became aware that ArcGIS For Desktop is available for non-commercial home use. At $100 it look's like a good value, especially because of the inclusion of the Spatial Analyst extension. One word of caution - this is the ArcView license level which is not nearly as rich as the ArcInfo level that many of us are accustomed to.
