mitutoyo, Brown and Sharpe dial, Starrett Dial
I would urge you to shop local pawn shops to look for where retired machinists have sold all their tools.
the Mitutoyo can be had used for around $79 or so, heck of a caliper.
The older Brown and Sharpe that has jeweled mechanism just makes you go, "SWEET" every time you use them!
The Mit will stay on 9 months or more if you do not turn them off.
