You don't need a tool to dish your wheel quite accurately; put a zip tie around one of your stays and cut it so it rests against the rim, then pull the wheel and flip it.
More accurate than a dish gauge that uses the axle ends rather than the locknut faces.
Not quite...flip flop method gets it close...especially if you rotate the axle to catch any deviations in low quality axles, cones and lock nuts. Once you go quality, or CNC end caps - that little caveat tends to fade away.
The dishing guage however avoids this as the arms rest on the rim - and you see the entire relation of the point to the axle entirely. Flip over and compare...done.
I do about a dozen electric bike wheels per years, my dishing tool is almost useless with some of the hubs used.
So I go the flip flop route. Set one way, rotate axle 360 - check the farthest and closest extent at which the rim is from the reference point...
Flip...rotate axle again...check the farthest and closest extent at which the rim is from the point.
If the extents are the same, dished - done. If not, got more work to do. I would say that I end up within a millimeter of being "dished".
The dishing tool is much faster...but there's an even more important reminder. Buy quality hubs to begin with - you don't have to put up with such annoying caveats.

I use the Park TS-2 so I have no way to guarantee that I've "snugged" a hub perfectly parallel in the arms. I bet someone here has a stand that does...
