Vertex tools have a good reputation. However, I bought a dividing head made by Vertex that had the chucks back plate periphery laser engraved, lines, 10 degree numerals and all.
Had I known they would take a shortcut like that I wouldn't have bought it. It took many hours to engrave them with the old Shizouka CNC mill. I should add that the fun I had doing the engraving was probably worth the trouble it took, but it shouldn't have needed that.
I also bought a Vertex 4 jaw chuck that seems nice enough.
