what skimmer to use

[Willito]

What brand of skimmer is everybody using these day? It's a question that is overwhelming me because of the many different makes, models, and the concepts that are available today. I am currently using a Berlin Classic but don't like it's mediocre performance. I want to invest into something that is highly effecient and will last me many years. I want to spend good money for a quality product but don't know where to start. Could someone with experience of today's up-to-date technology on protein skimmer, please advise me of the goods and the bads that are available on the market. thx.
