Two times is the charm, right?

(Closed the last suggestion as a c. widowmaker for 4 keys popped up and a prof. c. widowmaker was offered for 8 keys; turns out they were sold rather quickly)

Barely any without prof killstreak.

Could track 4 sales in the past month:

http://i.imgur.com/FeJBiXq.png Sold a chemistry set with 199 widowmakers for 8 keys (buds were at 15 keys at that time)

http://www.tf2outpost.com/trade/23641099 Sold for 20 USD on Community Market (~8 keys) ( http://i.imgur.com/AChJD4g.png )

http://www.tf2outpost.com/trade/23801703 3 keys; quicksale (I bought it)

http://www.tf2outpost.com/trade/23867420 8 keys http://i.imgur.com/PGK31ML.png (I sold it :P)

Yes, the last two were strangified, but honestly, that's the closest it can get to a pure c. Widowmaker as the prof killstreaks change the price too much.

Buyers:

-none-

BUT (1 week ago):

http://www.tf2outpost.com/trade/23092441 3 keys for 1 month (still no c. widowmaker in backpack)
