So my last suggestion got closed because the price decrease was too extreme. But, this hat SERIOUSLY needs a price change so, I've created a better range with more recent offers.

For Unusuals I will take their highest price on bp.tf and then multiply by .9 to cover overpay.

First off, the current owner purchased it for a max head and 2 buds which is~4.2-4.4 ( http://www.tf2outpost.com/trade/10561535 ). Let's say 4.3 buds

The unusual is one of one so I'll post the history of the trades of the current owner (~3 weeks long).

http://www.tf2outpost.com/trade/10574032 - 1st trade Taking nothing lower than 6 pure but, no offers.

http://www.tf2outpost.com/trade/10601761 - 2nd trade, B/O of 10 pure, no offers

http://www.tf2outpost.com/trade/10639888 - 3rd trade, B/O of ~7.5 buds pure, only official offer of a PE Conquistador (~2.7 buds)

http://www.tf2outpost.com/trade/10684395 - 4th trade No B/O and no offers

http://www.tf2outpost.com/trade/10734658 - 5th trade, B/O of 8 buds pure but no real concrete offers.

http://www.tf2outpost.com/trade/10940783 - #6 Most Recent Trade. 5 buds pure "quicksell" and still no takers

(offered to sell on reddit for 5 pure as well a few days ago http://www.reddit.com/r/tf2trade/comments/1f5d49 and recently http://www.reddit.com/r/tf2trade/comments/1fdes4 only asking for ~5buds, could go lower?)

OFFERS OF:

Memory Leak Dragonborn = No price set

Purple Energy Barnstormer (No offer in comments, private add?) = No price set

Smoking Softcap and Tricorne (No offer in comments, private add?) = ~1.8

Max Head = 2.2-2.4

Offers of Blizz Storm Trophy Belt + 1 bud = ~2.3-2.4 buds

Stormy Storm Brainiac = ~3-3.1 buds

Green Energy Tree = ~3.6 buds

Steaming Killer Exclusive = ~3.8-3.9

Orb. Fire YWN + 1 bud + #99 Head Warmer (no good prices for craft numbers, but bp.tf is VERY generous and says 2 buds) = ~4.2 buds

Nuts n Bolts Brainiac = ~4.9 (high end)

So for the low end I put 4.3 as that's around what it sold for last time. High end is the offer of a Nuts n Bolts Brainiac which is the highest offer the thing has gotten in 3-4 weeks.
