RO systems.

What should I look for in an RO system?

Im looking on ebay and a 5stage/3filter system is like 100 dollars, I thought they were much more expensive.

They very greatly in price and quality. I don't know a great deal about buying RO units but this is what I have found to be things to check out, customer reviews, availability and price of replacement filters, production and the amount of water it will waist producing the rated daily production.

Others may have things to add. This is all I could think of at the moment.
