The best skimmer i have ever owned is a cheap looking POS that i bought at the aquarium in apopka. It is made by sealife systems in Jacksonville. It is the most consistat skimmer i have owned in 20+ years. It pulls 1 1/2 cups every day out of my 90g. It doesn't look like much, but it is a skimming fool. I don't think regardless of how much you spend, you will find a skimmer that can out perform it. I paid $200 with the pump, and it is just a simple donwdraft skimmer. He has one on his big display tank that you can see how well it works.
