That I'm afraid that is more of a luxury because of the upfront cost and it has it's own list of cons too. You could be right about long term depending on how often you have to replace the cell and how much salt you go through. One negative for me is dealing with a 40lb bag of salt, where as I can handle 128 oz jug.
"Installing a chlorine system for the pool only costs about $100 to $400 (mine is a HASA feeder 200.00 investment with parts either lifetime replacement or cheap), but installing an electrolytic chlorine generator can cost up to $2,500. The generator cell, which ranges from about $200 to $700, will also need to be replaced every few years in a saltwater pool."
Of course some of you pool professionals I know get some freebees. I'm told the cells don't last as long in our Arizona high temperatures too. My neighbor had a really nice pool with spa, then he put in pebble tech and salt system and I looked over the fence to find it empty and falling apart, wow! That scared me! One of the issues is you really have to keep a close eye on the PH level on salt systems. Salt is not environmentally friendly either if it gets in the soil, Calif has banned home salt water systems.
