Price last updated 3 months back.

Currently only 2 available on market, no B/O below 3 as its availability is very low.

Looking at words by other seller it is not going to be sold below 3 pure

i purchased mine in trade for my GBH titanium tower for which we both agreed to set B/O as 8.5~9 (bracket are my paid prices)

I received beamsDread (3), beamsHetman(1.8), blizzParty+smoking mullet(2.3+.7), and S.gunslinger (1.1)

I would add more proof but unfortunately there are no recent sales as the hat is rare to find and i cant consider sales before 3 months as the hat was last priced 3 months back. If i manage to track more records i will add in comments but for now i think these proofs are enough.

One more proof,

It seems the beams Hetman and beams dread was sold together for green energy dragonborn(3.7~4.8, avg.4.3) 2 weeks ago [between 28-7-2013 and 29-7-2013]

Trade link http://www.tf2outpost.com/trade/9511115 [B/O was 3.5]

History 28-7: http://backpack.tf/id/76561198058078421?time=1374994800

History 29-7: http://backpack.tf/id/76561198058078421?time=1375081200

Item history: http://backpack.tf/item/1701749367 (Dub to Archfiend)

So if green energy dragon is considered 4.3(average price on backpack.tf) then the dreadknot and hetman were sold for 2.8 and 1.5 respectively although it is fact that green energy dragonborn is only one for sale by the same person and his B/O is 6 [it is possible Dub considered it 4.5 when he sold]
