What ground defenses besides Missle Launchers? Marines in pillboxes?

There's the dirty little trick of setting up supply depots at the entrances to your base and placeing pillboxes behind them. Units will run up and turn around, most of the time, especially Zealots. I also place siege tanks on either side inside my base but you have to be careful because the splash damage will also hurt your supply depots. I rarely use air units...too much time to build the structures and upgrade everything.
