Take a look at the RODI systems offered by Bulk Reef Supply. I bought the "75 GPD RO/DI 5 Stage *PLUS* System" from them about 3 months ago, and have not had one problem. I had water running out of it 30 mins after I received it, and it has great reviews. It arrives with 4 different setups for the tap/in-line/faucet. Great buy in my mind. It is still running 0 TDS.
