http://www.airwaterice.com/ or just Ebay. I didn't get the DI, because my water coming out of the R/O is at 4PPM. Buy any unit and you can buy a bigger membrane and ristrictor to handle it this is what I did. I got a used Coralife and it was only a 50gpd. I bought the set of filters and 100gpd Membrane w/ristrictor for 55.00 dollars shipped.Remember the that the R/O technology has not changed much and or the standards. Make sure it has the standard housing and the 10" housing for pre filters and your golden.

Theyre all the same more or less, brands matter little (dont pay for a name). Get/make a 5 stage and tds meter. Worth every penny.

 

Yes TDS a must have.

 

Yeow. Please be careful with some of the advice in this thread.


1. We'd strongly recommend you stear clear of ebay unless you are 100% clear and certain on what you need, what you don't need, and the ins and outs of these systems. I can't tell you the number of ebay systems we've rebuilt for people once they understood what it was they bought there.


2. All systems ARE NOT created equal between vendors. Again - you have to know what you're looking at to tell the difference.


3. Unless you have a specific water quality issue you're dealing with, you need only 4 stages. Add more stages only if you have a particular issue you are trying to address.


4. Here are some things to look for in a good system for this hobby:


No more than 4 stages (sediment, carbon, RO, DI) unless you have specific water quality issues you want to address

Standard-sized prefilters, membrane, and DI cartridge

Brand name, high-rejection membrane

Specifications provided for each stage

Pressure gauge after the prefilters and before the membrane

Thermometer

TDS meter (handheld or in-line)

DI bypass

Vertical DI stage

Refillable DI cartridge

Aluminum bracket

Quick connect fittings

No water from pressurized storage container delivered to DI

Flush valve

Clear housings

High-quality instructions written in clear English

Customer support before, during, and after your purchase

A vendor involved in your hobby

I have a Buckeye Field Supply 4-stage RODI and I love it. Took me 15 minutes to have it up and running out of the box.

 

Russ good advice, but all we are saying is if you know what you want then ebay is a great source. Buyer beware is in place for all retail outlets. .
