Open Source - EER Modeling Tool

Is there a good open source or reasonably priced EER modeling tool for MySQL besides MySQL Workbench? I find the MySQL Workbench interfac开发者_StackOverflow社区e to be clunky. I would like to be able to manage my production schema beginning all design changes in the EER and propogating those out to my schema for created and altered tables. Is anyone use a tool they love to manage their environments in this way?

Thanks. - Nick

Maybe you can try SQL Power Architect or DBschema. I never used them but got good feedback.
