Free at Linear Technology, a premiere maker of opamps and ICs. LTspice is a very powerful Spice implementation with very good plotting and analysis tools, and a great library of models that can be added to. Highly recommended.
ARTA, for those interested in *complete* audio analysis, offers a multitude of functions and can be run in demo mode as long as you wish with almost no restrictions -- there are a few limitations, but only a few. Also highly recommended.
