Any opinions on water softeners? All the 'big time' places like Costco, Ameriflow, etc. have given me quotes for 3K+ saying about how it's so great doesn't need maintenance blah blah, 5 year warranty, etc. None of them seem to have a real reason to say why I shouldn't get a cheaper GE unit for $300... I could replace it every 6 months and still be ahead. I guess I don't see the big deal in going through an extra 20 lbs of salt a month because of a less efficient timed or metered recharge cycle, it's what like $2 in salt?
