I would suggest to look on the sc skimmer, I believe they have 3 different sizes, I'm recommending what I had used. They're cone needlewheel impellers, low power consumption, cheap to replace pumps and they're very affordable, I had one, never regret I had it, lots of skimmate.
But if you want something more expensive look into the reef octopus, they have great costumer service and will help you even if you've purchased second hand, I purchased mine new (opened box) but they have no issue sending me parts.
And if your budget allows you get anything better yet than this two brands.
