My two cents.....
You really need to become a member for Basecamp Leasing. Its something like $125 buck for the year. This allows you to see new leases a week before non members. Believe me when I say potentially good leases go quick. We tried baseamp without becoming member and lost out on some really (potentially) good looking properties. To be honest we couldn't believe how fast they go.
The $$$$ per acre is another story. I never really compare prices anymore because we finally found property we really like.
