I don't know anything about the RO systems, but have been looking at Camping World at the two different water softeners they have. One uses table salt and the other uses solar salt. I believe this be good for calcium buildup deposits and would be cheaper in the long run. The water in Florida is very hard and leaves spots on the shower door and clogs up the faucets. CW has the best prices that I have found on the water softeners and will get one when I return to Florida next month.
