I own one now, so I was interested to see what this went for.

Sold for a Disco Beat Down Katyusha(1.4 with Overpay)

http://backpack.tf/profiles/76561198024348289?time=1400828400 -> http://backpack.tf/profiles/76561198024348289?time=1401346800

1.4 is a perfect middle range for 1 and 1.7, hence the price.

Additional Proof/Counter-Proof/Feedback/Constructive Criticism is always appreciated.
