Mechanical or electrical gauges?

Since 1969 when I got my Drivers, I've had oil-pressure failures, cooling system failures and charging system failures. And the gauges never ever told me anything that I didn't already know. So I vote the cheapest gauges you can find, cuz after the novelty wears off, you will rarely look at them.lol. Until something goes wrong. And by then you will already know what.

I like having the gauges to verify that I'm running ok...

Then if you hear the lifters collapse, and look down and see NO oil pressure, then you know to immediately shut it off before doing any damage to the engine... (Been there - done that and saved my 340 when an oil pressure relief valve stuck...)
