Ideas on new skimmer

[steve fedyk]

I'm looking to up grade to a better skimmer, and would like some input.
I have 120 G reef setup with sump and refugium, total Volume is about 150 G.
I have a bullet 2 right now, and is very loud and doesn't work as well as I would like. My stand is 42" tall and about 38" of clearance under my stand.

I've been looking at Bubble king mini 300 and Bubble master. Is anyone using one of these and if so how well is it working for you.
