Second Suggestion :)

http://www.tf2outpost.com/trade/14668497 (35 keys = 1.75 buds) (<1 day) (no offers)

http://www.tf2outpost.com/trade/13603110 ( 2 buds ) (1 month) ( highest offer = 1.75buds)

http://www.tf2outpost.com/trade/14207371 ( 2 buds + 18 keys = 2.9 buds ) ( 3 weeks highest offer= 1.83~ buds)

http://www.tf2outpost.com/trade/14282381 ( 2 buds ) (2 weeks) (no offers)

http://www.tf2outpost.com/trade/14294777 (Looking for offers (highest = 1.65 buds) (2 weeks)

http://www.tf2outpost.com/trade/14588316 ( 2.2 buds ) (5 days) (highest offer = 1.95 buds)

http://www.tf2outpost.com/trade/14674052 (37 keys = 1.75 buds) (9 hours) (no offers)
