I got a system. I wouldn't mind holding on to like 3 stages of it or would be willing to sell the whole schmo. It has 2 dual TDS meters, 2 DI canisters dual 75 GPD RO's and a bunch of spare filters but I don't have any resin. I don't like changing filters LOL! I had taken the RO's out of the system like a year ago but I assume they are still good as they are still in the canisters.
