What recommend addon SQL Management Tool?

Can anyone recommend some SQL Management Tools to augment with ScriptCase for a more streamlined development approach when it comes to designing databases, establishing relationships, creating views, stored procs, functions etc…

MySQL Workbench

navicat is good too, it just isnt free.

Thanks guys, seems Navicat would be a great companion app to scriptcase…
