I would not waste my money on a sea clone. I have a MyReefCreations MR-1 becket skimmer. That thing skims like a mad man! Their site is www.myreefcreations.com the builder names is Andy great guy. I also bought both my Mag 9.5 ande Mag 18 from them.
I really like those skimmers my other favorite but pricey is the Deltec skimmers. They rock also but they are a needle wheel skimmer. Two different designs and two great companies!!!
