Figured I'd see if there are any used ones floating around before I buy new.
And while I'm at it, I would greatly appreciate thoughts as to what exactly is necessary, nice to have and an outright luxury. This will be my first RODI system and so far I'm thinking of going with the Vertex Deluxe 100 GPD. I like the onboard TDS meter, reduced waste water and smart system for redundancy.
