Gauges!! -- Mechanical or Electrical ?

[Red514LX]

This spring/summer I'm going to be fitting my lx out with some basic gauges: fuel pressure, oil pressure, temp., etc.

I like the look of the Autometer Pro-Comp Ultra-Lites (White gauge faces).

Should I buy the electrical or mechanical type? Should I also opt for the liquid-filled gauges?

Here's the criteria:
-I want the most accurate version
-I'd like them to last the life of the car
-They will be mounted INSIDE the car in
the typical vent slots or heater slots

Price and difficulty of install are NOT important.

Thanks in advance. All replies appreciated!!
