Headband and Sash for Iksar Monks?

[TheFishyOne]

I am a 42 Iksar Monk with no desire to farm Brother Qwinn for the Robe of the Lost Circle. My Qeynos faction is more or less untouched, save that I have trashed my corrupt guards factions, and I have trashed my Freeport faction by leveling off of guards in HHK.

I have discovered that killing the orcs in WC raises Ashen Order faction, and I figure I can FD my way to the FP monk guild hall to earn my sash (or just fork over 900p in tunnel), but am not sure how to raise my GuardsOfQeynos and SilentFistClan faction. Purple headbands seems to be rare (and quite expensive! 3k+ for one...) in tunnel, so I will prolly have to just get faction and do the quests. Have any other Iksars gotten their own Purple Headband? If so, how did you grind the necessary faction?

Many thanks in advance!
