Looking at these in my Travers catalog, I see one made by Blake
for $200 and one by Phase-II for $110. If I were to buy one of
these, is the Blake worth $90 more than the Phase-II? The Blake
goes from 5/32 to 4 1/2 and contains only 2 feelers. The
Phase-II looks like it has at least 6 feelers. Even though the
Phase-II is a Chinese knock-off, generally the Chinese measuring
instruments have been found accurate.
Opinions.....?
