I'm pretty sure I can drop this one with B/Os instead.

Seller at 14 Keys: http://www.tf2outpost.com/trade/26105016 1 Week unsold

Seller at 17 Keys: http://www.tf2outpost.com/trade/25701794 Almost 2 Months unsold, no offers

Seller at 20 Keys: http://www.tf2outpost.com/trade/26115652 1 Week unsold in this trade, but has actually been unsold for 4+ Months: http://www.tf2outpost.com/trade/24008062

If it can't sell for 17 Keys for almost 2 months, 14 Keys is probably a better price than 20.

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