Short of a Wally Tractor, you can't go wrong with the protractor from Turntable Basics.
As an aside (and to lure Doug Deacon into the fray), Tri Mai at Triplanar specifies the same protractor which he gives away with his tonearms.
I'd prefer that the scribed lines would be a touch narrower (as they are with my unobtanium mirrored protractor), but at least this protractor is mirrored.
Then again, Frank Shröder uses a piece of card stock.
In the end, it's as much the craftsman as it is the tool.
Cheers,
