In my experience, the Turntable Basic protractor is fatally flawed in that it does not permit the user to precisely locate and align the spindle with the pivot point of the tonearm.lewn FYI, the VPI alignment jig does just that... what it does not is give you Baerwald.
All of the protractors you mentioned are good, but they are not free like helomech's option... I'd rather spend my money on LPs, but that is just me...
If you print an arc protractor on photo paper, it will give you the same precision as the Mint, minus the mirror for azimuth. For those of us who care about $130....
