I'd like to push back on continuous integration being over-complicated. It's easy to do using off-the-shelf software and it makes life a lot less stressful when you have confidence that your changes are good before landing them in production. It's such a win that I'd set it up even with a 10 person team.
I use TeamCity to automate running my unit tests and generating/publishing NuGet packages to my private NuGet server... and I work alone. It has value even there. :)
