Cost to convert? Prolly a grand in hardware.
Cost savings? HA!

I have a salt water pool. I do not believe there are any cost savings at all.
Ya gotta run the pump longer, so that eats up $$$$.
Ya still gotta add acid, but now you gotta add more.
Ya gotta add salt, but that's nickel and dime.
Ya doan hafta add chlorine until summer comes and it gets hot. Then ya hafta supliment, or run the pump 14 hours a day.

And when the chlorine gererator takes a dump, it's gonna cost ya. Replacement cost for mine is $750 at the pool store, $550 on-line.

The real savings is in convenience.
It's nice having the pool take care of itself at least a little.
It's nice being about to have a clean pool with lower chlorine levels that you can barely smell or taste.
But I believe if I converted it back to conventional I'd save money just in the electricity alone.
