Here's a couple that I have:
Interapid 312B-4, which I bought after selling off the Starrett No.711 Last Word kit that I'd bought new in about 1984. I tired of the Last Word's habit of shifting the needle by about .0003" to .0005" every time I changed direction while indicating a bore or other task. It was also a pain to change the spring "direction" with the switch on the Last Word. This indicator is super smooth, needs no switching and does NOT shift the needle. Reading .0001".

Brown & Sharpe, unknown model number. I got this one from an employer who was closing up. It works better than a Last Word, but doesn't have interchangeable tips. You get what you get. No shift of the needle upon reversal, reading .001".

Here's photos of the one I use the most, a Starrett No.709AZ kit. That one is a .0005" reading dial test indicator with a big 35mm dial (1-3/8") and I gotta be it's only fan. The No.708 and No.709 have a reputation for being "quirky", but mine that I bought for $40 from a retiring Starrett guy is PERFECT and I love it. The dial rotates with a feather touch, much less force than the stiffer Interapid.
