Hi Sean, I understand your logic and agree on the cost per unit. However, when I used 3 inch tablets in my pool, I'd spend maybe $150 - $200 per season on chlorine (by the time I found this Forum and the BBB method, I had already installed the SWCG). My SWCG after install ran right around $1000. I just don't want anyone to think that the SWCG will pay for itself in one season. The way I see it, it will take me 5 years to break even. Oh and BTW, I love my unit for the convenience factor too. IMHO it was worth every penny.
