Interapid 312 B1: BulletProof!
See Long Island Indicator service on the web for tons of info on this and many others.
Rene is very helpful. Do not buy obsolete Interapids, parts are no longer available, i.e. 310 series.
You see them on Ebay, do not buy!
 
i own an interapid, its the bees knees, i do own a vintage last word, and there is nothing wrong with it, it does its job, its fallen on the ground (children) and i popped the lens back on and it still holds true... something to note about the interapid indicators, the reading is REVERSE of the common clockwise rotation. so it can take some getting used to.
 
Thats why I usually go to my best test. The Interapid has two rounds of travel though. Mine also has the larger dial on it. It does take a little getting used to.

Maybe everything else is backwards.. ;-)
Seriously though, in the 25+ years that I've been in this game, I've only used interapids, so I never noticed anything as being backwards. I always give the indicator a slight "bump" to check rotation depending on which way I'm using it.
 
Like others have said, 312 B1 is a great indicator. I have dropped mine a couple of times and it still works like new. I looked at a Chinese one cross eyed and it crapped out. Did the only fair thing with it, sat it on a fence post and got out the 30-30 and sent it to heaven without the virgin escort. I use Chinese dial indicators with no problem but they seem incapable of making a test indicator, odd.

Amazon Haas a mitutoyo yellow face indicator with a mag base and arms for around 33$. I bought the same set 6 months ago. It works well for me.

Machinists usually have an assortment of DTI/DI's for different applications, but for general purpose use i.e.
TIR, centering work, checking squareness, fixing a vise, etc.. which DTI is a good all around choice for a first
time purchase? .001, .0005, lever type, fixed?
 
I would say one 0-1" dial indicator that reads in .001 and one test dial indicator (tdi) that reads in .0005 will cover 98% of your basic needs.
 
I bought an Interapid used, but returned it. It needed some repair and cleaning. So now, I'll wait for
a good sale from Zoro or Enco and buy them new. One Interapid and one Mitutoyo. (and maybe a Starrett plunger type DI.)
I also want an Indicol and two Noga's.
Total: + $800.00
