$200 is the import version. The good ones are *MANY* times that. There are no specs on the import but the good ones are tenths reading/accurate. Often w/ replaceable templates so they work as a mini optical comparator (sort of a mini toolmakers microscope reticle.) They were used with jig borers and such back in the day.
You can probably throw that kind of accuracy out the window w/ a USB microscope if there are moveable focusing optics in it. They probably just dont track well enough to keep colinear. Remember the mount has to be adjusted for both tilt and offset so that distance from the workpiece doesn't cause errors. So while I agree they could be home built for < $200. Im not entirely sure its worth the effort esp w/ used prices well below that.
