Seller at 25 Keys: http://www.tf2outpost.com/trade/28268207

Seller at 26 Keys: http://www.tf2outpost.com/trade/28253385

Seller at 28 Keys: http://www.tf2outpost.com/trade/28217340

33 is the only useable sale I could find, basing the low end off of the lowest seller.

25-33 Keys should be fine.

Additional Proof/Counter-Proof/Constructive Criticism/Feedback is always appreciated.
