Not $600 but a good one .MAX50.. found out the hard way!! .. have a dual TDS meter ... do not care how accurate .. but on the way out it still says ZERO ... that is what I truly watch .. although the input is interesting ... numbers higher during high temps or rainfalls .. (town water) .I have done all water tests along the way (water in, water out, tank .. da-da-da-da ) and the RO/DI confirmed all that you have said .. again, found out the hard way (or soft, if you consider the hair algae!!).. .Tnx Tom ...Keep up the good work/info ...
