Some more sales:

5 pure - http://www.tf2outpost.com/trade/9733692 - duped one

4.8 pure - Noon appears to have paid 4 pure + 5 keys + 5.33 ref + 26 bp expanders? - http://backpack.tf/id/76561198048308168?time=1369983600

which would be ~4.8 pure. He claims to have paid 6 and is selling for 5.5 pure, but he is obviously valuing the bp expanders at a much higher price that he should.

~3 - hurr furr was offered a scorching hotrod + hound dog for his beams noble which would be ~3. Clearly an outlier - http://www.tf2outpost.com/trade/11175213

http://www.tf2outpost.com/trade/10879159 - and then there is this one that was traded 2 weeks ago - ~5 hats including the scorching hotrod for an anti-freeze gibus - damn!

Cool, thanks. That would be ~5 as well (steaming hermes ~1, bubbling bomber ~2, level 1 max ~2)
