Google can easily find price pages. The structure of a paid directory since it has section which a free one doesn't have.
However I think that google devaluates only low value directories which is different from paid ones. Google (and users) doesn't likes directories with no selection which includes almost everything, those are usually paid directories since you're paying you're in.
I see directories giving good boosts (in the old days), like BotW or business.com or yahoo. Just because they got a good reviewal process differntly from other directories. Actually I won't paid for any directory listing.
