Recommend alignment protractor


Hi,
Can anybody recommend an alignment protractor. I bought a geodisc, but now that I have it in hand, I think I may want something a little more precise. I'm using it on an Immedia rpm-1 table and arm (unipivot).

TurntableBasics.com sells a good two-point Baerwald protractor for just $20. The mirrored surface makes it easy to see and correct small cantilever alignment errors.

It would be nice if the TTB's alignment grids were scribed with thin lines rather than printed with thick ones. That's what the class-leading Wallytractor has, but the Wally costs $150 and there's often a 3-6 month wait.
I'm good with the ole DB protractor. But my favorite was the van den Hul mirrored one with a very fine alignment grid (I can't remember if it's scribed or not.) They used to come only w/ the cartridges, then they weren't available at all. Now they're available as an accessory from van den Hul USA for $20.

That's the first time I've seen or heard of that VdH gauge. It looks excellent, and nicely compact too. I may pick one up just for ha-ha's. Thanks!
