This sort of depends on what you want to do with the ERD.  If I want  
to document an existing system, I use Aqua Data Studio.  It's not  
free, but it will take an existing system and draw the ERD for you  
based on the relationships it finds in the database.  There are  
things that I don't like about it.  It puts the tables into the ERD  
in alpha order.  This leads to some spaghetti ERD's.  You can move  
the tables around and then save them.  The problem is that once they  
are saved, it's an image and you can't move them anymore.  If you  
recreate the ERD you have to begin again to move the tables around.   
Another tool that some people like, but that I haven't used is called  
SQL-EZ.  It's cost is trivial.
