I ran into Buck Hodge's post on TFS tools on CodePlex and I must say that I'm pretty impressed with the selection of free tools out there.

In particular, I like the Code Review Workflow and Automaton offer.  I played with Automaton today and for what is "there" it's not too bad.  There is still some room for improvement but it gives implementers a pretty nice start to allow developers to kick start a build.  As for Code Review Workflow, that's on the books for another day.

Another two projects to look at and consider are Source Code Tree Browser (this is one the features I loved from ClearCase) and Turtle (similar to Tortoise SVN).
