Closed my last suggestion becuase the high end price was slightly off.

1 of 1 on the market, Many others seem to hold on to theirs.

Most recent sale~ http://www.tf2outpost.com/trade/17897454

clean Cloud 9 Salty Dog for a clean Stormy Storm Honcho's Headgear(valuing at 1.9 buds) + 10 keys (.5 buds) + a specialized strange Baby Face's Blaster (Cheapest on Community Market is $5.40). (= to about 2.5-2.6 buds) accounting unusual overpay this would be around 2.3 buds. hella accepted Pobito-san~'s offer.

http://i.imgur.com/DPaemOS.png ~1.75 buds pure (rounding to 1.8) + S. Sniper w/ headshots, sniper kills, long distance kills. (Within range) If you check aqua's bp history, it does show he owned the buds/keys, and now owns the Salty Dog w/ C9.

hella bought it for 35 keys pure (1.75 in pure rounding to 1.8)

http://www.tf2outpost.com/trade/17482272 ~ =(eGO)= Poor Man's trade

http://backpack.tf/item/2299940010 ~ one of the 35 keys' history (going back 3 weeks in hella's bp history, showing he did indeed trade the keys.)

Any information that can make this suggestion better is highly appreciated!
