Download SVN For Windows WITH Apache Modules
I spent months trying to find a distribution of Subversion for Windows that actually included the Apache modules. The main SVN website maintains a list of sites that have binary packages for Windows, but they either didn't include the Apache modules or, like with VisualSVN, they were customized and unsuitable for use outside of the software they were packaged with.
I researched building it myself, but that got hairy pretty quickly as the source code (and the documentation) hasn't kept up with Visual Studio versions.
