SUCCESSFUL BUYERS <8 keys:

http://www.tf2outpost.com/trade/9782485 - multiple offers of 7.5, add at 7

http://www.tf2outpost.com/trade/9717887 - bought at least 1 for 7

Didn't actively look for more. These are just ones I stumbled across.

Still too early to suggest 7-8 since an occasional one will go for 8.5 or 9. Not including unsolds at 9 cause there are so many unsolds at 8. Its price should be 8 flat since that's what most are traded at.

If providing counterproof, please provide proof more current than the last suggestion (4 days).
