I teach electronics at a State College and have been using CircuitLogix for the past three years. During that time I've had about 200 students who have used the software in my courses, and they all like the user-friendly interface. SPICE-simulators are generally not too intuitive, but CircuitLogix has gone to a lot of trouble to make theirs easy to use.
There are two versions - Pro and Student, and both have trial downloads. I would recommend downloading the 30-day trial of CircuitLogix Pro since it also has a 3D simulator as well as another 2,000 devices and models.
