What Compression Tester Kit do you suggest?

[Burro II]

Mityvac has two. The fancy one for about $97 and the simple one for $32.

Harbor Fright sells a kit for about $30. But I'm suspicious of their stuff.

What do you suggest? None of my old school compression testers work on the deep spark plug well engines of today. I have a 4.7 and 3.7 and need to upgrade my tool box. I think I'm still in the last century.

Thanks in advance for your suggestions.

You might be able to buy an adapter so your old compression testers will work. I bought a Bosch model at Oreilly auto for $30 and it had a long reach adapter
