What do you use as a good alternative to Team System?

Question

I'm stunned that nobody has mentioned the free and excellent TeamCity product from JetBrains. It includes:

• Continous Integration
• Software Build management
• Project Management, Monitoring and Statistical Reports
• Integration with many IDEs, Sourcecode control systems, and Testing Frameworks

For project management / bug tracking / Git or Subversion repository I also use Unfuddle (free for small personal projects!)

I'll second Trac + Subversion. While nothing is perfect, this combination works quite well for me, and the price is right.

Even for projects I work solo on, it's nice to have both of these integrated.

I've had a lot of success with the nice integration between SourceGear vault and FogBugz.

MS Build for build automation meets my needs.

Took my answer out of the question and posted it as one of the answers per the StackOverflow FAQ.

Here is the solution that I use and it works great:

• Subversion for source control
• Warehouse for my Subversion web browser
• FogBugz for feature and bug tracking with it integrated with Subversion, Visual Studio, and Warehouse
• VisualSVN for integrating Subversion into Visual Studio
• CruiseControl.Net with nAnt for my automated build system for .Net projects
• CruiseControl.rb with Capistrano for my automated build system for Ruby on Rails projects
