To each his own I reckon, I'm partial to mechanical gauges and I run them from the front port of the intake manifold. A good quality gauge, elec. or mech will work just fine.

Any good gauge is fine. Taking the reading from anywhere on the radiator is not.
I always put the sensor in the cylinder head if at all possible with the intake the second choice. I have seen engines loose the coolant and melt with the gauge in the intake and in the radiator is much worse. What happens is the heads get very hot but the intake and especially the radiator may not be that hot because the coolant no longer flows over the sensor.
Anything downstream from the thermostat is almost useless because a stuck thermostat will cook the motor and never warm the water in the thermostat housing or radiator.

I'd have to second the mechanical gauge! It's nice not to have to worry about electrical issues too, when your worried about the true temp. of your engine.
