Look for a Local Roush Distributor in your area, they can get in Roush products much cheaper than what RPP sells them for. As for pros and cons, I like them. Have had them on for over a year now. Only comment I have. Make sure when the window mounted hinges are attached, that Adhesive Promoter is used and its on a nice warm day so the hinges will adhere firmly to the glass. I had to re-do my two top outside hinges because of them not adhering properly to the glass. Used 3M Automotive Tape, Adhesive Promoter, warm day, warm glass and some pressure. All is ok now. Somebody else recommended putting a bead of clear silicone around the base of each hinge where it's attached to the glass to deter water from getting to the tape. I'll be doing that soon. All in all I'm pleased with the Roush Louver. Looks nice, no rattles, secures firmly and is easy to lift up and has 2 attached prop rods to hold up the louver for cleaning glass.
