Finally my first unusual suggestion. Thanks to blind polar bear and Asianeer for the help finding the solds!

There are only 2 on the market currently. One is below and one is Asianeer's and is too new to be criticize for no offers ;)

Sold:

http://www.tf2outpost.com/trade/16026242 Sold with 20 keys for Purple Confetti

Hat With no Name. Original price of HWNN = 2.9-3 buds. Minus 20 keys but buds were 17 keys at the time so ~1.8 buds

Selling:

http://www.tf2outpost.com/trade/15390020 Had an offer of 2.3 pure when buds were 17 keys so ~2 buds I believe today. He also states that he is willing to do 2 buds pure later on, but no decent offers.

Please, Its my first time at an unusual suggestion (woa green belt) so please provide constructive criticism.
