ER RS180 vs. Oct Extreme 200 vs. Vertex IN180

I've been doing a lot of research trying to pick out a skimmer for a 120g w/40g sump setup that I'm planning. Important features for me are noise (quiet as possible) and energy efficiency.

I was leaning towards to the Euro Reef for a long time, but I've heard that the GenX4100 pump on that skimmer is very loud. I've also read about a lot of other problems with this pump.

The Vertex also looks like a decent skimmer, and is cheaper, but it seems to be an energy hog.

The Octopus Extreme would then seem to be my best choice, but I don't have a lot of information on it, the RC thread seems to be all about mesh modding the thing, which I wouldn't be into. Would this be a decent skimmer for the begining reefer?

I know this is like asking a crowd for their opinion between Chev., Ford and Dodge, but I could use a little advice to tip the scales.

Thanks!
