Many offers of 1.66 are turned down, as well as 2 ref offers. Needs a small rise.

Yes, I own one. No, it doesn't matter.

http://www.tf2outpost.com/trade/6911355 2 offers of 2 refined in the last 2 weeks.

http://www.tf2outpost.com/trade/6750673 Offer of 2 ref one day ago.

http://www.tf2outpost.com/trade/9209064 2 ref offer a week ago.

http://www.tf2outpost.com/trade/7247814 Offers of 1.66, 2, even 2.33 at one point.

http://www.tf2outpost.com/trade/9558094 1.77 offer turned down.

http://www.tf2outpost.com/trade/9428752 1.66 offer turned down.

However, there is still at least one seller at 1.66:

There's also at least one buyer who has gotten offers of 1.66.

So there you have it. Sellers willing to sell at 2 ref, buyers willing to buy at 1.66 ref, and the occasional 1.66 seller. It seems very possible to make a sale on either side of the range, so that's why I've put it in.
