Ro/Di units

[NbMaxx13]

I am trying to find some affordable Ro/Di units for some people just getting into the hobby. I am trying to encourage some good habits. I will suply all of the media and membranes, I am just looking to see if any member of the club happen to have one laying around... I do and just donated it , and now I need 2-3 more... Not looking for freebies , just trying to see if there is a deal to be had... Thank all , let me know..

Spare parts would be a big help as well...
