I don't have prices off the top of my head, but there is a shop in the South East corner of Luna (maybe a building or two south of the actual corner, with vendors on the roof) that sells these kinds of suits - Luck and LRC combos, good resists etc. You might want to check their prices. I'm not on Atlantic anymore but that shop has been there for a long time (and was there a couple weeks ago still before I moved!)
