It measures each of the three sides of the rotor.
Reads it out digitally and is ******* expensive.

Don't you mean remove the spark plug? These engines have no valves. The mazda tester will give you a seperate compression number on each rotor face. I'd think that an analogue guage would be good for a quick check (as long as it doesn't hold the peak #), and will let you see if there's a broken seal, but won't be that good for determining the actual compression numbers. I wouldn't advise buying a rotory tester, just take the car to a shop that has one and have them do it.
