Murf,
If you just want the best available sharpener on the market just get an Edge Pro either the Apex @$125 or the Pro @$275. Both do the same job, the Pro is just built better.
If you only sharpen knives every month or so then another may suit you better....however, if you want the best the Edge Pro is the way to go IMHO! It is so simple to use and you put a perfect edge on every time at whatever degree angle you want to.
