There is no mystery in setting up a turntable correctly. The weakest link in the chain is the person doing the setup. If a tonearm's geometry is correct and it is mounted spot on, all that is needed is an overhang gauge. I made my own as there is not one on the market that suites my needs. It fits over the spindle and was calibrated for my arm on a lathe. There is not aiming things at the horizontal pivot or lining up the cantilever with fine lines. Once I find my the right VTA for a cartridge the gradations on the tonearm's shaft allow me to return to the same spot instantly.
IMHO all that other stuff is wasted money. The Wally Skater in particular would make Rube Goldberg proud. I can do exactly the same thing with a digital VTF gauge.
