I finally made the purchase, around $140. This is a nice sharpener. The directions are a must read. It also takes some practice to get used to. The directions tell you use a "practice knife" and I would also recommend this. There are several different belts to choose from but they made it easy to change them out. They are supposed to last through many knives. Don't know if that's true yet. Previously I used a Lansky Sharpening system and that was good but it takes a while. I believe if you need a knife sharpener and use knives quite often, this may be your ticket. Not worth it for most who only use knives once in a while.
