First of all, I have not had any experience withe Berlin skimmers, but I have heard/read really good things about them. I use Euro Reef skimmers and think they are great. You might want to consider one. They are easy to use, basically plug and play. From what I know, I don't think you can go wrong with a Berlin, they have a really good reputation for a reason. I think once you get into the price range of a Berlin or Euro its personell preference at that point since these skimmer do a good job. I might be totally wrong, just my opinion.
