Theres nothing wrong with having high quality tools. But not real nescessary in this aplication though. We don't need to prove to the FAA that our engines are good enough to power an airplane through the sky. We just need to know if the valves or the Rings or the head gaskets are leaking. I use 100 PSI in my low cost Summit tester and it tells me what I need to know.
