The brand of RO system has almost nothing to do with the quality of the output.
TDS
Temperature
Pressure
Required output
All of these determine what you need. Don't get trapped into the fiction that more $ means better water. Once you know the requirements above you can get amore accurate answer.
In the example above with 10ppm TDS in the lower BC region you may be able, providing you have 60psi or greater at the source, be able to use a 3 stage 50gpd unit as the membrane will have a reject rate of greater than 90%, in some cases more than 95%, so if your other water parameters are good and you monitor the pressure pre-membrane and the TDS post-membrane.
