Alright, there are only 3 trades selling this on outpost.

http://www.tf2outpost.com/trade/7905758 - has offer of 2.33 refined

http://www.tf2outpost.com/trade/7926770 - has offer of 2.55-2.77, "not selling for metal"

http://www.tf2outpost.com/trade/7840300 - white one, wants 9 ref

Also, there's my trade where I've been trying to buy one for 1.66 for a month. Only one post and he managed to sell it before I could get to him. http://www.tf2outpost.com/trade/7117652

This needs a price buff if people are offering 2.33-2.77 on people's trades and they're still getting turned down.
