The one that fits your situation and works for you is the best choice.
..oh, and fits your budget.
Don't spend more than $200 when you could get a used kickass one for $50.
Euro-reef -- from the looks of them -- look effective enough. Lots of tweakability. Might be a hassle but looks like it'll do the job right. I'm still waiting for someone to design one with a cup that has a banana bolt on top to keep the skimmate and airpressure from popping the lid off the collection cup... open skimmate cup = stinky house.
One suggestion and I'm sure everyone can agree with me on this -- don't buy the regular Red Sea Prism skimmer. All issues with all skimmers shine crappiest with this skimmer.
