My pool is an in-ground style, 2 years old, so this opinion is based on it and may or may not apply to your pool:

A salt water pool does not save money. It wastes money.
It is nothing more than a convenience thing.
Chlorine generators are expensive. Up to $700 for the fancer ones, $300 for the cheaper ones. They often don't last that long. Maybe 3 or 4 years.

The cost of acid at least doubles with a salt water pool, plus you still have to buy some chlorine in the hotter months unless you want to pay $$$$$$ in electricity costs.
I have to run the pump at least 10 hours a day in the summer and still have to add a 3" tablet or two a month to keep up. To make all the chlorine it needs I'd have to run the pump at least 12 hours a day in the summer.
You end up paying more for the electricity than the chlorine would cost! Plus the chlorine it generates is not stabilized and burns off really easily.

I love my salt water pool, it's very low maintenance and the water is crystal clear and doesn't smell like chlorine. But it would be much cheaper if I just eliminated the generator and took care of it myself.

If you change to a salt water pool I bet you change back within 7 years. Everyone I personally know who had a salt water pool has had a generator failure and has changed back to a normal pool instead of paying $$$ to replace the gererator.
