I use Tru-taper. I use the collection of cheapies I have as shaft gages. I like the consistency of the Tru-taper. I find the plastic cheapies get deformed by shafts that are not exactly to spec. Then, in my experience, the arrows that are in spec will come out..not so good.
For cutting wood arrow shafts I use an Exacto miter saw..it is a tiny thing. The saw is based on their classic red plastic handle. Mine is special because it is old, rusty, and bent (8 y.o minimum). And the arrows come out perfect.
