I started using it when it first came out. It is nice and flexible and easy to use. Many of the various best practice ideas you will find on the forum are incorporated and ready to use. It has good documentation and is easy to customize. I would highly recommend it to just about anyone.
Given what it would take to set up something like it from scratch, I think it is definitely worth the cost.
