I'll throw my crafting hat in here, too. I can make a few enhancements:
Advanced Battle Enhancement 30
Advanced Quick Savant Enhancement 30
As well as nearly all the craftable color crystals (Black-Blue, Black-Red, Black-Orange, Black-Purple, Cyan, Purple)... except for Purple Indestructible. >.>
Send a whisper or ingame mail to Padraic (Republic) or Thesquer (Imperial) - I'll gladly craft for mats or for a below-GTN price.
