I don't know if it's worth swapping for an electric. The main reason people do it is so that offroad when the engine is spinning at low speeds, an electric fan can spin at whatever speed is necessary to move sufficient air through the radiator.

About a year ago I was of the same mindset and had gone as far as to draw up a cost sheet of how much I would have to invest to make the swap happen. With this new radiator I don't think that it is really needed anymore.
I say this now, but if I find a good quality Taurus fan in the junkyard while looking for my electric replacement, I may change my mind
. Still, if I'm remembering correctly, the fan wasn't the expensive part... the PWM (pulse width modulator: which controls the fan speed) to run the fan most efficiently was at around $200-ish.
