So I needed a roof rack, and decided to go with the MegaMule from
http://bajarack.com. This is a new company, and I haven't heard much feedback about their products. I've got it on the factory roof rails (for now). The rack is steel, lightweight, and was easy to install. I had about 350# of pea gravel and topsoil on top this weekend (far overloading the factory rack capacity!), and it did great.
Here are some pics:
