I think it is a fair deal. For forced induction it would be pretty hard to do much better than $2k for a complete kit with only a few months use. Although for the same $2k there were some very good naturally aspirated options listed in this thread. Of course I have my biases. When you add in the cost of a header (~$400), you are getting closer to my suggestion in post #14 for a fully supported, brand new, and complete turbo kit.
It sounds like you made a commitment, so I wouldn't sweat it. Get it. Get it installed. Drive it. It will be a learning experience no matter what you do. I don't think you will be disappointed.
