The Mint protractor is okay but it is for a single cartridge, single pivot-to-spindle distance.  The DB systems has a stylus landing spot that is too big for real accuracy.

Believe me, that last little fraction of a millimeter, that's not where its at.

Actually, it is.  The difference between "close enough" and accurate can be sonically astonishing.  Get the most out of your cartridge.

MINT Tractor and a pair of 3-4X reading glasses (to obviate the use of a lupe).

Did own MINT and threw it away. SMARtractor is pretty good.
Also Dennesen Protractor.

Dr. Feickert latest protractor, nothing else. This is a tool for every tonearm and every cartridge/turntable with all 3 alignment method on it to choose one you like. The most important: it have precise pivot to spindle ruler. It's German quality and not so expensive, some others cost more. The best way is to buy used Feickert if the price for a new is too much for you. 

Then a Hi-Fi Test LP and Cardas Frequency Sweep LP.
