If my 293-345 1-2" with the ratchet thimble wasn't such a great deal, that 293-336 is what I would have.
This seems to be about the cheapest.

I think I'll have to make do with what I have for now.

I put together a set of S/H Starrett 436 metric mics covering 0 - 200mm. One doesn't have a lock on it but it doesn't bother me, as I take the reading before I remove the mic from the part. Come to think of it, I tend to do that with those that have locks on them as well.

For those micrometers I have without locks or electronic displays, that's what I do most often.
One of the myriad features of the Mitutoyo Absolute digital electronic micrometers which dearly love is that "Hold" button. Get the micrometer touching just right, thumb that button and loosen the thimble to remove it from the work. Your reading is still there. Hit the Hold button again and you're back to direct reading.
Life is good.

That's easy to do with the electronic micrometers but not so easy with vernier micrometers. Or maybe I'm just unskilled at reading them.

Use the lock most of the time. Rather than going by the feel of the load on the spindle, i'll get what appears to be the measurement then close the mic maybe a half thou and feel the drag as I slip it over the shaft.
Free advice is worth exactly what you payed for it.
