Your wife is a smart lady. You won't regret the SWG. All the major ones have their pro and cons. I personally think the Pool Pilot Digital is an excellent unit and also think the Goldlilne Control units are sturdy perfomers! The Zodiac LM3 is a bit less expensive and Ihave not heard anything bad about it. If you choose a unit that offers different sized cells oversize your cell! You can run it on a lower output and it will last longer!
