I bought my RO/DI unit on ebay from the following seller:

Great unit, easy to put together and cheap. I highly recommend getting the unit with the water container, this gives you 3 gallons of water available quickly at any time, otherwise waiting for 3 gallons to be filtered can take 30-40 minutes depending on the membrane size, temperature and water pressure.
There are even cheaper models on ebay, worth the expense considering what we spend on everything else and the control it allows you to have over water hardness and PH in your tanks.
