Thule 832 Surf rack

Hi, I have some Thule roof bars on my car and have been looking for a decent solid and safe way of taking my boards to the beach so Ive been looking at possibly getting the Thule Surf board carrier 832.
Do any of you use this rack on your cars - if you do, is it worth paying the extra or would you rather have saved some cash and just got some tie down straps?
I cant seem to find any reviews from actual surfers on this item, maybe some of you can help.
Cheers in advance
