I love Vertex products. It's definitely the one I would prefer; however, after researching the Aquamaxx as a stop gap until the Omega 130's debut I came to realize the ConeS CO-1 is a pretty beastly skimmer.
They seem to have done a lot of research to put together a nice package at a nice price. It's compact with easy access to the pump. The individual cones really seem to be cut the turbulence down and force the foam straight up the neck. The collection cup with the tapered neck and a handle is nice as well.
This thread has a nice review

after 2 weeks it was pulling some nice goop on a 39 gallon system
It's currently sold out everywhere. I figured if I could get one in the meantime, I could just sell it when the Omega 130 comes out.
