The price has moved on. Most of the trades are happening at 1.66, and in recent days, 2 ref has become more and more common.

Here are the links at 1.66:

Everything higher is unsold, meaning that this is the correct range.

http://www.tf2outpost.com/trade/6712397 - Selling for 2.33 ref

You'd struggle to find a seller at 1.33. There's enough evidence of trades at these two prices to justify a range between them.

And for once guys, don't be mystery down voters. On almost all my suggestions there are ~5 people who down vote without posting a comment. If you have a valid reason why this shouldn't go through, tell me! Others can follow your lead - if you're right.

Let me know what you think :D
