RO/DI units?

[bheron]

Hello,
I saw this line in a previous thread and figured I should just resend it:
"I have a RO/DI unit that I have fixed to automatically top off my tank"
This sounds like a great product!
- How much do they cost (approx)?
- Where can I get one? Online stores?
- Can it also be used for gradual or full water changes?
Thanks for any help!

i got my Ro/unit at Lowes ($200 includes tank). i have it under the sink in the kitchen. pretty easy set up for a DIY-er. It makes a gallon per hour at 45 psi.
