Going cheap would probably be more hassle in the end then its worth. get quality stuff or you'll regret it.

I picked up about 1-3 MPG depending on the type of driving.

If the fan alone costs $350, and it requires a $100 controller, and you get at least 12mpg now, and the best you can get is 3mpg increase (which I don't believe, but we'll just use it), and gas costs an average of $3/gal, that means you'd have to drive at PEAK economy for 9000mi just to pay for the parts. But you've gotta figure in labor even if you DIY, and you can't drive that efficiently all the time, so just plan on this being a losing investment for at least 2 years. And if you get more MPG than 12 right now, it'll take even longer.
But an e-fan is NOT more fuel-efficient than a mechanical fan UNLESS the PCM is programmed to turn it off when it's not needed. An aftermarket fan controller can't do that.
So if your only goal is to save money, leave the mech fan on.

E-fans would be independently controlled they are not controlled by the pcm.

The reason they're not more fuel-efficient is that they take MORE power from the engine than a mech fan, when they're moving the same amount of air.My '94 CV's e-fan is PCM-controlled because I swapped in the complete engine, wiring harness, e-fan, & PCM from a '00 MGM. So mine is actually more efficient than the original '94 engine & mech fan.
Most E fan conversions are not PCM controlled they come on when the temperature reaches a certain point via temp sending units. Turn of when the temp reaches a set level. most kits set up for one fan to come on when the A/C is on. Thats it.
The whole idea is gaining power and fuel economy by reducing parasitic power loss.. Loosing the mechanical fan gains horsepower (dyno proven gains of 15-20 hp)
