roof rails

Anyone ever order/use the roof racks and rails off of AliExpress or ebay? Seems one could order the whole kit-n-caboodle with rails and crossbars for about half of what OEM would cost. I can't imagine they could screw it up too badly. Any opinions on quality or preferred sellers?

This weekend I added the factory roof rails. It didn't take that long maybe an hour and a half. I think for me the hardest part was making sure the rubber would stay on the aluminum rails. Also doing it in 28º weather didn't help ;) Next up, fix that nasty horn.
