If you follow this URL http://www.mathomsolutions.com/freestuff.asp?LangID=1, you will see a list of free SQL Server tools for DBA's.  Most of these tools I have used in some form or another and all are quite good.  This just proves that expensive does not always mean quality. 

Please support these individuals as they have given their time and effort to create a quality tool and make sure to respect their license agreement.  Sometimes, a note of encouragement or telling them how their application helped is worth more than money (although money is still nice).  However, most of the time a compliment paid from a fellow DBA, is worth tons!

If you would like your tool listed, just drop me an email with your name, a little bit about your application and where it can be found and I will get it added.
