The commercial SICStus Prolog is also substantially
more expensive (see
http://www.sics.se/isl/sicstuswww/site/index.html), at
153 euros for a Personal License (see
http://www.sics.se/isl/sicstuswww/site/order4.html). 
Prices for Academic, Single-User Commercial, and
Multi-User Commercial licenses are even more
expensive, at 1560, 1980, and 7800 euros,
respectively.  An Evaluation License is only valid for
30 days.

Not all students and researchers can afford a Personal
License.  Can you recommend an alternative, fast
Prolog development system under a free licensing
agreement, such as GPL/GLPL?
