Welcome to this excellent forum of Yeti enthusiasts.
I got the Skoda roof bars fitted to my Yeti as part of the deal. No idea how much they cost but they do look really great and seem very sturdy. They don't overlap the roof and they have nice Yeti logo's on the end of each bar. There are loads of pictures online of you google them.
My Skoda bars were fitted as part of the purchase deal and I am generally very happy with them, though some noise at highway speed, as to be expected. Very quick to fit and look good, but noticed yesterday, when I had trouble getting an end cap to lock on, that this was caused by the mounting bracket on the carry bars not sitting flush against the inside of the roof rail. As mentioned in posts elsewhere the Skoda bars are rebranded Thule units.
