The Georgia Aquarium is using RK2 skimmers. They are a big vendor in the commerical arena. We saw them at MACNA and they said they were just getting ready to launch a "hobby sized" line of products. One of the things they had there was this sweet combination Sump/Skimmer/Fuge. It was really nice but just a prototype
I'm not sure how their smaller scale products are but I gotta believe their commercial stuff is pretty good because they've been around for a while.
