Query: Works well on good knives

I have always sharpened my knives with a ceramic rod sharpener, but it seemed to not be working so well anymore. Cooks Illustrated recommendedChef's Choice M130 Professional Knife-Sharpening Station, Platinum, but I was not going to spend $150 to keep my knives sharp! Luckily, this one works fine. I found it a little difficult to keep the angle right to keep the indicator disks spinning through the whole length of the knife, but it sharpened them fairly quickly -- only about 10 strokes needed per slot. Like I said, I have kept my knives reasonably sharp already, so they needed less work. And I have only used the sharpener on my Wusthof and Henkels knives, which are better to start with than what others might have. But keeping that in mind, this is a good bet for the home cook.
