I'm using Treek on a low level Shadow and so far so good. It's nice to have a healing comp at low levels. Mine came with 2 sets of fully moddable LVL 10 gear.
My Sorc wears the grey version minus the dress I know for a fact that the Black Hole weekly rewards you with 2 versions of it. You can also try the GTN and search modded armour chest piece in the Light category.
