After much research and procrastination, I finally decided it is time to increase the quality of my shooting. I just purchased a Hoya Pro 1 CPL filter. I don't quite understand why B&H sells this filter for $186 and I bought the exact same thing for <$70. It is an OEM Hoya filter with the same p/n as the B&H version. I like B&H, but, their prices seem to be somewhat high on some of their items. Can't wait to start using it for my landscape shots.
