Phono Protractor. Recommendations?


After purchasing a new Cartridge recently, I'd like to purchase a good protractor.  There are so many available, each claiming to be the one to have, I'm confused.  
What do you recommend?

Point B is just to verify that point A is correct. if point A is perfectly lined up then point B will be perfectly lined up. if point A is slightly off then point B will be slightly off.
