Who has a SWC 160 Cone or Skimz Kone SK181?

[Myka]

Can anyone explain the large cost difference between these two skimmers that seem to be fairly comparable? Anyone have any comparison reviews? It sounds like the Skimz pump is a better pump, but $225 difference...? Hmmm...

This skimmer would be replacing the EuroReef RS-180 that is currently employed on my ~100 gallon reef. The ER performs well, but is very noisy and likes to overflow.

Skimz Kone SK181
Skimmer pump: 1 Skimz ES2000 needlewheel
Power consumption: 12W
Air intake: 540 l/h
Rated: 50-200 gallons
Price: $500 (I think??)

SWC 160 Cone
Skimmer pump: Atman 2500
Power consumption: 27W
Air intake: 650 l/h
Rated: 100-150 gallons
Price: $275

I would prefer the SWC 180 Cone, but it has a Sicce pump on it which I refuse to buy. Anyone know of a replacement pump for the SWC 180 Cone?
