EBay RO/DI Units, Looking for Feedback

Next on the list as I accumulate equipment and deplete my bank account is an RO/DI unit. Would any one be so kind as to provide their experiences/recommendations with EBay sourced units? There seem to be at least a couple of providers. Unit would be needed for a 72 gallon tank with 30 gallon sump and a drinking water set-up would be preferred. Areas of interest: ease of installation, installation support, performance, maintenance. Will be running well water (probably 60F and 45psi) with some iron and reasonably high nitrates through the system.

And my stupid question of the day: any downsides to drinking RO/DI water? Health? Taste? Anything?

Thanks everyone.

i have an aquasafe canada ro system 100gpd, it did not come with a di unit but i bought one for $40. it's great!

i dont think you can drink water if it has a di unit on it. but you can put a stop valve between your ro and di sections so you only drink ro water. thats what i do.

It won't do you any harm to drink it.. it just might taste a bit stale. A final stage carbon filter should make it a little more appealing.

The one down side to running a R/o or and Ro/Di unit is that it takes 3 gallons of water to produce one gallon of purified R/o water.

I bought a 110 gpd unit from filterdirect on ebay. Great filter. It's set up so the ro filtered water goes into a holding tank for drinking and also has an outlet line that goes thru the di filter that I use to fill up my containers for top offs and water changes.

I too have a 110 from filter direct and so far it's great. I did not get he holding tank though...I have no need for it and it saved me a few bucks and a few feet of space. I have never heard a bad thing about these ro's and they are pretty cheap comparatively so I recommend it.

I got the 110GPD FilterDirect RO/DI unit from eBay. Easy to install and it seems to work fine. I'm thinking about getting a TDS meter to monitor the performance. Anyone use one? Any recommendations.

Yep, picked one of these meters floating around on ebay. Works great.

In case that link didn't work, it's the HM Digital TDS/Temperature meter.

I was also wondering about these systems. Do you guys worry about the availibity of replacement filters/membrane for the Ebay units?

Is using a TDS meter the only way to measure the performance of a RO/DI system? And has anyone done tests for the Ebay units?
