What is the best Knife sharpener on the market?

What is the best Knife sharpener on the market?? Im looking for one that will sharpen all kinds of kitchen knives and pocket knives. One that's not very expensive and that will put the PERFECT edge on a knife. I have one of those Accu sharp things. It works ok but i want something more "professional". I also have a LANSKY KNIFE SHARPENING SYSTEM but its not all that good either. If anyone know a GOOD knife sharpener like im looking for please let me know what kind to buy, how much it costs and where to get it. Thanks
