+1 for sharpmaker
The video that comes with it will give you a lot of background info, and you don't need a lot of skill to get decent edges with it. Great for the price. You can also place the triangle stones in the base and use it as a quasi-bench stone to practice that as well.
I also own the DMT Aligner kit (the magna guide for the dialfold, and the one with the four inch stones). It's good too, and easier to maintain angles, but longer to adjust and use.
If you get the magna guide, you might also want to buy a DMT angle mate... it's a cheap piece of plastic that you attach to the diafold and helps you get the right angle on your stroke. It helps train your hands for when you don't have anything else or are 'just' using a stone.
I'm collecting/testing sharpening gear in 2009 as one of my preparedness items (heck, I even got a hunter honer, a smith's abrasives pocket pal, gerber ceramic $2 jobbie.. bestglide tungsten carbide for emergency field use, etc).
The only reservation I have on the sharpmaker is if you have messed up knives (kitchen knives with decent size nicks, etc), you'll need something coarser then the brown stones to remove metal, unless you like growing old waiting for your tool to be usable.
They make diamond stones for the sharpmaker (~$50), but lots of folks buy a DMT blue (coarse) stone, 6" or bigger, to do the repair work and then move on to the sharpmaker. I have the ultra fine (some say 8000 grit equivalent) for the sharpmaker, but I don't see myself buying the diamond hones for it. I'll be getting the DMT coarse bench stone.
These are just my 2 cents, taxable in Ohio. Hope it helps!
