I switched to a SWG a few years ago and love it. The "conversion" is simply installing the SWG and adding salt, done. I can even use bleach and turn off the SWG any time I want, and I do that when opening in the spring and when shocking the pool (which isn't often). Other than using the SWG to produce chlorine, I'm BBB all the way.

I've done comparisons of the total costs of the SWG vs bleach and they all come out more or less even. Depending on what you count as part of the SWG expenses, and what you don't count, it can go either way. Having a SWG is way less work and it makes going away for the weekend much simpler. I'd be willing to pay more for that, but I don't have to.
