Recommendation for gauges?

[Xplantdad]

I'd like some opinions on aftermarket gauges for my Chevelle. I'm specifically interested in the oil pressure, water temperature and possibly volts.

I want something that's fairly inobtrusive...so I was thinkng about getting something small and digital like these




What's better, mechanical or electronic? Pros and cons of both? I remember my hard lined oil pressure gauge burst inside my old Nova...it was a plastic tube if I remember right...wasn't any fun

Thanks for any advice offered
