I was going to close the last one myself and resubmit, but oh well. 7 of these in existence, 3 on outpost, overpay is calculated in all instances.

http://www.tf2outpost.com/trade/12309210 - Sold for Cloudy Jeepcap(~4.6) + Vivid Fullmetal Drill(~4.2) = ~8.6 buds

http://www.tf2outpost.com/trade/11742574 - (old sale) Sold for Cauldron Company(~5.5) + Blizz Stash(~1.8) + Planets Snaggle(~19 keys) + Planets Toque(~20 keys) + Steaming Bonk Boy(~2.2) + 1 pure = ~12.3 buds

Here is all those unusuals he traded for: http://www.tf2outpost.com/trade/12047986

http://www.tf2outpost.com/trade/11669521 - offer of:

-(old offer, bought another hat)Burning Drill + 3 + 2 bills(TS/B) + sweets = ~14.5

http://www.tf2outpost.com/trade/12932213 - B/O of 10 buds, also worth noting he bought this hat for a terror watt brainiac, a 1 of 1 hat for which he had a B/O of 8 buds for.

http://www.tf2outpost.com/trade/12397090 - offers of:

-4 pure + stormy brainiac(~3.1) + 0.5 sweets = ~7.6

-Harvest Cowl(~7.7)

-Secret Medic Ushanka(no price, probably at least 8)

-Cloudy Moon Hoodie(~8.4, outdated but the hat is getting offers in the 8-10 range)

There are 7 of this hat, so a flat price didn't seem appropriate. Two different B/O's set at 10 each set the ceiling for the prices, making higher sales or offers null. The hat seems to get offers of 8 and above, which is why I set the low end as 8.

I'm always interested to hear everyone's opinions.
