If you're setting up Subversion and Apache, and you are not using VisualSVN Server, you're wasting time.
A year ago, I spent 3 days learning how to install Apache, host Subversion in it, and configure all of the users for my system. Today, I downloaded VisualSVN Server (all of 6 megs), started an instance of my Win2k3 Virtual PC image, installed VisualSVN Server and added a repository and a user. Total time spent: less than 10 minutes from download to using my repository. Of course, I don't have LDAP authentication configured - but that's only another 20 or 30 minutes (copy & paste from existing Apache config files).
