11 Month Old Price, has never been updated... 1 of 3 on OP, but one trade is looking to upgrade their mining light to a better effect.

TRADE 1:

Offered 39 Keys + 3 Ref (Roughly about 1.6 Buds)

TRADE 2:

http://www.tf2outpost.com/trade/10646545 :

OFFERS:

Offer of 1 Bud, a Black Bill's, and 8 Keys (About 1.6 Buds)

SOLD HATS:

http://www.tf2outpost.com/trade/11149532 - Sold for 1.5 last week

Overall there hasn't been many other offers to price this hat at, so a solid 1.6 Buds seems to be fair. The few other offers have been to low for the owners to consider.
