I picked up the Rhino 2500 rack with Aerobars online from autoanything.com for $233.40 plus shipping after discounts. It's comparable quality to the Thule, and the Thule accessories fit the Rhino bars. I have a set of Thule ski/snowboard carriers mounted on mine.
I've had many Thule racks in the past (including OEM racks made by Thule), and these Rhinos are of equal quality for almost half the price. I'm very happy with them!
