Craigslist! You can find 500+ dollar rack setups for 100-200 bucks all the time. I literally have a large drawer full of Yakima and Thule components, and a shelf full of all the attachments. I have ran Yaks or Thules on all of my cars, and paid full price at REI exactly once. You might need to get the fit kit for the control towers if you buy used though.
