As many folks have said, the Sharpmaker is a great tool for maintaining an edge, but not all that great for getting a knife from *dull* to sharp. If you want to do that without taking a ton of time, there are a few options.
One option is to pick up an Edge Pro and a diamond for it. I've got the Atoma 140, and it cuts steel
really fast. Of course, you're looking at some bigger money to do this, but it's a good investment long-term. Also, it packs down pretty small so that when you visit parents/relatives/etc you can take it with you and touch up their knives, which is always appreciated.
A faster, but more dangerous option is to pick up the
Harbor Freight 1x30 belt/disk sander and a few higher-quality higher-grit sharpening belts. This is more dangerous in that a) it's a power tool that you can hurt yourself on if you're not careful b) it removes material very quickly, so you can ruin a knife if you're not careful c) it potentially can ruin the heat treat if you aren't careful (notice a trend here?). On the other hand, you can go through a pile of knives in very little time and take them from super-dull to very sharp, then touch them up later with the Spyderco you've already got. The other dangerous part, btw, is that you'll get tired of the limitations of the little Harbor Freight and want to move up to something smoother/bigger.
Finally, there's the classic option of buying some bench stones and learning that way. If you can do it, more power to you... but the sander is still faster.
