The Deluxe DMT Aligner system used to get my knives shaving sharp.
Although it's not nearly as advanced or as well built as a Wicked Edge, It still packs a punch for it's price.
You can also get an Edge Pro Apex, which is slightly cheaper than the Wicked Edge.
There's also the Spyderco Sharpmaker which is a pretty good system.
But most of all, I would suggest learning to Freehand, It's such a useful skill, and a full freehanding setup could cost you maybe 100-150$ Which is much cheaper then a high end guided system.
Plus, if need be, you can freehand in the field, which you can't do with the WE or Edge Pro.
Coarse + Medium + Fine + Ceremic (Ultra Fine) + Very fine sandpaper (2500 - 3000) gets me some amazing edges. And is fairly cheap.
