I've been ussing CC.NET for probably the last 5 years with good success. At work, we recently migrated to TFS 2010 (installation and configuration are brutal, but it's sort of nice when it all works). I figured I'd take this time to look around and see what I've been missing on the continuous integration scene for my personal projects. The 2 leading contenders were TeamCity and Bamboo. I went with TeamCity since I use ReSharper, and think the JetBrains guys are pretty top-notch.

Installation was drop-dead simple. Configuring was pretty straight-forward, but I had an assist from StackOverflow, which led me to this amazing article/series by Troy Hunt. After following Troy's instructions, and slightly adjusting for the obvious version differences, I had things up and running, with a completed build inside 15 minutes.

I also configured the Build Triggering step because I want the build to fire off each time I checkin. I've got a few things to take care of (notifications of broken builds, code coverage, etc.), but it looks like this is a much easier application to configure than CC.NET.
