ER Modeling cowboy style

I'm looking to model some tables just for the pretty pictures, no need to generate a database or anything of that sort. The project doesn't merit going out and buying some sort of tool like ERWin (or Visio), but I'd still like to be able to model the tables and relationships (including cardinality).

I've been using Microsoft Word to some success, but am not, as you can imagine, entirely happy with it. Has anyone had success with any other tools (free or a prominant desktop application)?

Thanks for any experiences you can relate.
