We've used the Wood-Mizer re-sharp service for a couple of years now, first from the Kentucky location and now the Missouri location. We have been very pleased. The blades come back sharp, set, clean and lightly oiled and ready to use. They cut better and longer than the blades I sharpened.

I can make money at about 5/1 ratio over what the sharpening cost vs. spending the same time sawing. And I suspect we gain the cost of the sharpening just in the better performance.
Even if I don't have sawing to do, I about rater have my teeth cleaned while listening to rap music than to sharpen blades.
We've sold our sharpener and setter to some Amish brothers with a Wood-Miser mill. We're both happy.
