Nothing wrong with using a different gauge.
Personally I do not like liquid filled/dampend gauges for this job. When I used a Injector/Pop Tester in a Fuel Injection Shop watching the action of the un-dampened Gauge Needle/Pointer was important. I would not have wanted anything to slow the movement of tne needle down.
One of the tests was with the Valve open you slowly pushed down on the Handle and you would watch the Gauge Needle rise slowly. What you wanted slowly to see was the Injector Nozzle not leaking and that needle to go up to what ever the Pop Pressure was the Injector suddenly open and the Needle very suddenly fall. And, if that repeated evey time you did the test your Injctor Nozzle had an extremly good area where the Pintel seats in the Nozzle.
And, in fact Commercial Injector/Pop Testers do not come with a dampened Gauges and as you have seen the Dampened Gauges cost about the same depending on what country they come from so I doubt if it is a cost factor.

It's only my opinion from a home users perspective, just in case folks are thinking of building one
I am sure the pro's have this down to a fine art, my local Bosch shop uses a digital contraption housed in a large perspex case with lid.
It appears to record the different phases automatically similar to say a rolling road BHP test. What would be useful is a marker on the gauge which records the 'high' leaving a secondary needle in place. This is something I have on my compression tester.
