yeah, you can get malaks armor. it's +7 defense and +4 dex, restricited to DS, strength +1 and regen +2, and is upgradeable.
the other great robes really depend on what kind of character you want to be. for lightside, Nomi's robe, with defense 3, wisdom +4, and regen force +3.
for sith marauders, Crado's robe with strength +6...but const. -2.
But i'm pretty sure the ultimate robes are Aleema Keto's robe, defense 3, rest. to DS, strenght +2, wis. +4 and regen force points 1,
and for all you neutral dudes, Jolee's robe has regen force points 1, and 31 defense.
