Mini-suggestion for Scorching Flames Heavy Duty Rag*:

There aren't really any more recent valid sales that I could find since it was last updated.

The price is just about a month outdated, so it shouldn't make too big of a difference.

http://www.tf2outpost.com/trade/27416333 - C/O of Australium Sticky/Grenade + SF Ambassador + Sweets = ~41 keys

~Will be taking a value of (46*0.9) = 41.4 (rounding to 41 keys)

Notes:

http://www.tf2outpost.com/trade/26898300 - B/O of 75 keys (2 months+)

Conclusion:

Two valid sales at 70 and 61 keys. Taking a final value of 61-70 keys.
