I bought mine at eTrailer. I got the Thule Aero rack. I have owned Yakima and am not a fan of the round bars. Thule has a less expensive line that is square, but I really like the look, functionality, and ease of installation/removal of the aero bars. It was about $330 shipped. I thing the other Thule system is about $280.
This is the only pic I have taken since the installation:
