Definitely needs a price bump with offers and successful sells of 2 buds or more. Hell even gifted ones are getting offers at or above the current range.

Very young trade. Was offered a SF Rocket (1.7 +/-) if he added, and 1 bud + 18 keys + a Bills (1.96 buds).

Was offered 34 keys, 35 keys, a Smoking Surgeons (1.8-2.2), and a Steaming Samur-eye (1.3-1.5).

Apparently sold for 40 keys based on the rep the seller left on the buyers profile. Its hard to tell with this sites and tf2items history by incomplete.

From what I could tell it looks like the buyer got his keys from another trade just before trading for the Raincatcher and that's why most of the keys say a different previous owner.
