I got a good response to this one, and as you can see, it was also fast. I managed to get data for all the IL townships and section boundarioes for all counties except Jo Daviess, Madison, Jersey, Calhoun, Tazewell, Mason, Alexander, Pulaski and Massac (does anyone have *section boundaries* for these?) The most-often cited URLs were: The National Atlas http://www.nationalatlas.com/mld/plss00p.html This has 1:100K township boundaries available for download in shapefile format for all states that use this system. Unfortunately, they don't provide section boundaries. Illinois Natural Resource Geospatial Data Clearinghouse http://www.isgs.uiuc.edu/nsdihome/webdocs/browse.html This is a good place to start searching for free Illinois GIS data. However, the PLSS Coverage here is the same as at the National Atlass site; townships only, no sections. Also mentioned were: The Land Survey Information System http://www.geocommunicator.gov/GeoComm/lsis_home/home/index.html This one has a nifty map interface to the download, but nufortunately there were only 6 townships listed for ILlinois, and since they were from a 3rd party source, you couldn't downlaod them. In the end, I got the township boundaries and most of the section boundaries e-mailed to me from list readers -- very convenient!.
