hmm not sure how i feel about this. There are currently 4 on the market.

http://www.tf2outpost.com/trade/18029342 - Specialized killstreak so cant really be used

http://www.tf2outpost.com/trade/18031251 - selling as a set, but is by the same seller as the one above, so again cannot be used.

http://www.tf2outpost.com/trade/17131729 - no buyouts posted, but no offers in 2 months

http://www.tf2outpost.com/trade/18466412 - the trade you posted above, 4 key buyout, 2 weeks up.

I guess its hard because there doesnt seem much interest at the moment, and there are only 2 that are clean. I just felt a little wary as there is only one trade proof, but looking at the lack of interest and the fact that even with 4 keys as buyout for 2 weeks it looks like it might not even get 4 keys. So i am going to have to agree.
