Current mid-value is 29.36 keys, yet a fair amount are available for less. Suggested price: 25 - 28 keys

Unsold at time of me posting:

http://www.tf2outpost.com/trade/10538637 (28 keys, indicates that three are available)

http://www.tf2outpost.com/trade/13814492 (bud + 4 keys = 25.5 keys. Michael owns 8 of these, not sure if he's selling multiple or only one)

http://www.tf2outpost.com/trade/12810582 (29 keys)

http://www.tf2outpost.com/trade/12442017 (29 keys)

http://www.tf2outpost.com/trade/13102554 (27 keys)

http://www.tf2outpost.com/trade/13670060 (re-list of the above, selling for 27 keys. Owns three. Trade is younger than the previous)

http://www.tf2outpost.com/trade/13670264 (26 keys. Based on the history it appears to be duped)

Sold:

http://www.tf2outpost.com/trade/13397309 (had a 1 bud 6 key buyout 2 weeks ago)

http://www.tf2outpost.com/trade/11718486 (offered it here for 21 keys. Michael is the current owner, I'm guessing he bought it for that price)

Summary: Doesn't look like 29+ key sales are happening.
