That's all the sellers at 2 keys and down, also the not recently bumped ones.

Buying:

Only one useful for now is this one:

http://www.tf2outpost.com/trade/8287917 - Offered a painted one for 1 key + 3 ref. 1 week ago

Conclusion:

No success at 2 keys, and willing sellers at 1.75 keys (including me).

So 2 keys shouldn't be in the range since people can't get it sold for that.

Thanks for reading, I hope to hear what you think and vote, and have a nice one.

Ps. Sorry that I'm trying to sell, I know some people get mad if the suggester is a part of the proof, so sorry to those guys.
