Amazon has a tri-stone Smith's system for $20 if you want a cheap stone system that will give you a good range to learn to do it by hand

or if you REALLY want to do pull through, for $25, you can get a Smith's adjustable angle on amazon (adusts from 14-25 degrees), which you should be able to match to the becker grind

BUT I still prefer my lansky..You can get the 5 stone kit (with natural stones) for $30..seriously, I can put a mirror polish on my edges with this kit...that said, I have noticed a fair amount of wear on the stones over the course of sharpening all my various knives multiple times. Also, it is a pretty slow process with the natural stones. To do it all over again i would get the Lansky with diamond stones and call it good and skip the rest of the sharpeners..

Oh, one other thought, the spiderco sharpmaker is basically a crock stick sharpener. If you don't want to spend $40 on it, I know smiths and lansky make something very similar for $14-20
