Cylinder compression tester?

In another post I've reported that for the first time today I've used my 40+ year old Gunsons "push and hold" compression tester.¬† Gutted that it barely worked on one cylinder before giving up the ghost.¬† If I can find the original receipt I may make a warranty claim.¬†ūüėĄ

What tool do you guys use for this seldom needed but valued piece of kit, any recommendations?

I have a very old Hawk, a bit like this. Sadly the front fell off, it still works and the red thing still rises to the same place, at what I remember to be 150. The important think is not so much the reading, but how close the cylinders are to each other.

The seller is either an American Indian or a poor Chinese cook... "running noodles"?

Incidentally how many of the 12 pieces have you ever used?
