I had a mini 160 and now have RE's new double cone 130 x DC. Nice little skimmer. Skims very well with that DC pump!
my opinion is just my opinion, but of the two BK skimmers I've used, Royal Exclusive sure does use some premium materials to manufacture their stuff. Very weighty PVC, nice thick acrylic and pretty much perfect joints (not to mention red dragon pumps). Their PVC and acrylic edges are all polished as well. The Akula skimmer is on par with BK build quality and they even have beefier PVC. The Akula i own just isn't as polished on the edges of the cup like the BKs are. It sure does skim well though! The Ultrafeef Akula and Typhoon skimmers use their custom Sicce pumps. I guess they're made special because it's a dark green sicce with transparent volute on mine. Never seen a Sicce like that before!
When i bought my Double cone i saw some crazy stuff coming down the pipe on RE's Euro web site. They have some crazy new mini'ish 160 that's coming. It has long diffuser tubes coming of the bubble plate. Kind of like a super long version of the aquamaxx bubble plate cones. Interesting stuff!!!!!
