What do you all recommend to be one of the best least expensive RO units on the market. I am in the market to buy one because I am tired of spending the high price to buy the water each week. Also I wonder by the time you buy the unit what cost you actually make the water for and how many gallons they will produce. I appreciate any tips anyone would have. Or if someone has a good used one for sale including the cartridges.
Thanks,
