Got mine and have been putting edges on everything I, my dad, and my brother own. Get the newer Ken Onion design.
When you get it, don't start with the finest grit belt thinking you are going to put a sharp edge on that knife you think just needs a bit of sharpening. It will most likely be a slightly different bevel than what is on the blade so work your way through at least three of the belts to get that new. Bevel on without wearing out the fine belts.
Once I figured that out things really sped up in putting the edge I wanted on the blades.
