I see that some of the free "data flogging" websites are now flogging the free 2007 TIGER/Line files (SHP format) for $100+ bucks! OR.... you can always simply go to http://www.census.gov/geo/www/tiger/tgrshp2007/tgrshp2007.html for your self and take a few minutes to download these data yourself - sounds like a no-brainer to me!
About the data... The 2007 TIGER/Line Shapefiles contain current geographic areas (boundaries of governmental units as of January 1, 2007) and Census 2000 vintage geography. The shapefiles also contain some additional post January 1, 2007 feature updates reported in the Boundary and Annexation Survey (BAS).

A tip, if you want fast access to an entire county's data, simply copy/paste the url of a file that you want to download and then trim off the filename.zip. You'll then view the directory folder for the county with all the .ZIP files for fast, simple download. A tool like GoZilla is also handy for quick site eating of data!
