We have never had one before and have been just fine without one. On the other hand, would the savings on our Air Conditioning related electric bill be reduced enough so the vent would pay for itself over a reasonable period of time? Any feedback from fellow Villagers who have first hand experience with these vents would be greatly appreciated.

I am in the "No" group.
Besides (as already mentioned) the expense, potential water leaks, not knowing if it's actually running or not, consider the air that is being sucked from the attic.
Not a lot, but the air being sucked out is not replaced with only outside air, but also the conditioned air from inside the house. Comes from air leaking into the attic from the fans, ceiling vents, lights, etc.
It could actually increase your air conditioning load.
If you must, I would think a static vent or two might be more practical, but even then the house was engineered to have the attic air flow that it already has.
