Has anyone found a quality locking gas cap for the 06? Thanks in advance.

I don't know what the quality of it is, but the Stant 10506 has worked fine on my 05AC since May 05. Cost $15 or $16 at Pep Boys

Have you purchased a locking gas cap for your 06 Tundra? I'm currently looking for one and the parts house and Stant website list a 10509 as the right cap. But many people on this site have been using the 10506 without problems. Which cap did you get and why?
