Here is a cool, free tool from Red Gate (whose products I uniformly love; they're a great company): SQL Scripts Manager. As they describe it on their Web site: SQL Scripts Manager is a free tool that brings together must–have scripts from expert DBAs, SQL Server MVPs, and Red Gate developers to enable you to automate common troubleshooting, diagnostic, and maintenance tasks. The product initially provides 25 scripts donated by some of the biggest experts in SQL Server, and the tool lets you directly run the script or examine the source to see what it does. And it hooks into Red Gate's SQL Server Central community site to share your own and download other scripts.
This is a great resource, both for the tools it includes and the possibilities for learning from the masters. And the price doesn't get any better!
