I bought my RJS camlocks from Summit for $109 with racer discount. When I got them the tag was already 3 months old so I called and complained they gave me another $30 off! I just had them recerted for $49 and that included return shipping and had them back in less then 7days!!

RJS has one of the smoothest operating camlocks, Gforce and simpson are also very good.
I have RCI platinum camlocks in my dragster and I don't like them much. The webbing is so stiff they have belt "creep" I had to zip tie the lap belts to keep them from moving. The only good thing is they are reasonably priced and come with one free recert.
