Actually, I have SAM, SAL and a PG2000 fiber optics illuminator in my pool/spa now. My builder has finally gotten around to finishing things and repairing the damage he did and has replaced the FiberStars uinits with the Pentair ones. From what I have seen I like them (The colors are more pastel then the FiberStars units and the color wheels turn slower...a more pleasing and relaxing effect)
