I've got the usual assortment of sharpeners, some purchased, some received as gifts:
Gatco Edgemate, Spyderco Sharpmaker, DMT Diafolds, Gatco Tri-Seps, Diamond Rods, Meyerco Sharpen-It etc.
I find that I don't enjoy using the clamp-on type (Lansky/Gatco) sharpeners at all.
(I use the stones more freehand than with the rig.)
The Sharpmaker (imho) is the most useful of the fixed angle type sharpeners in my experience, but I haven't used nor am I interested in the EdgePro or Skarb. There's just something about simplicity.
I also like the Diafolds and Tri-Seps quite a bit; as well as the diamond rods (for recurves).
Nothing seems as rewarding as freehand sharpening, and though I still have a ways to go until I can consider myself really proficient, I am in the process of getting Spyderco's ceramic benchstones in all three available grits (medium, fine, ultra fine) and a DMT Duosharp (X-coarse/Coarse) benchstone to provide assistance with tougher steels or reprofiling/repair.
Though the cost of the benchstones will be the same as an EdgePro (for example), the advantage will be the enhancing of my skills as a sharpener, no need for messy oil/water, and stones that will last for years and years if used properly.
Anyway, this gives some idea of what my own personal progression has been like in this arena.
