Linear Technology has their LTSpice/Switcher Cad III available for a free download.
It's a very good package for linear circuit modeling.

Texas Instruments has TINA-TI available for downloading. I haven't used it much; many people like it.

There are a number of entries in the Electronic Resources forum; have a look here:
