I would think just about any gauge that's not a "$4.99 special" would suffice.
People have certain preference/opinions about electric vs mechanical gauges. Personally, I prefer mechanical gauges, BUT I wasn't in the mood to take a chance running a plastic tube with hot oil in it up & through my A-Pillar. So I went with electric for the "safety" factor. I installed a mechanical oil pressure gauge also (just mounted it below my dash) for a few weeks just to check the accuracy of the electric unit. To my suprise the electric gauge read only about 5 psi lower than the mechanical. Once I had a good reference point, I took out the mechanical gauge.
