I have always liked Euroreefs, Aqua Cs and Deltecs in general. Aqua C has fantastic customer service but tends to be a high energy consuming design. All three brands are fairly easy to setup and get reasonable skimming results IME. Of course here as on most boards, you ask what the best skimmer is and you will get dozens (eventually hundreds) of opinions. Quite a few great skimmers out there, pick one you like and learn how to setup/mod it for maximum effectiveness.
That said, I just got a SWC 160 cone to try out on my new half cube build. It was pretty inexpensive and looks well made...but we'll see how it works. I'll post when I can say more about that.
