Take a look at the EdgePro system at http://www.gorge.net/business/edgepro/default.htm
I have the 'Professional' model, and it's something like the Lansky system - in the sense that a 2000 lb. bomb is like a firecracker, since they both go 'boom' and can hurt your fingers.
Using this system (or the Apex) you can easily match ANY sharpening angle and hold that angle almost irrelevant of the amount of pressure you want to use. These suckers are SOLID.
I also have the Spyderco Sharpmaker system, and this is, in my opinion, the best sharpener available for serrated blades. It's pretty good on straight blades, and very quick, but the EdgePro system is MUCH better for accurate, reproducable sharpening of straight blades.
