Long story short, I want to buy a RO/DI unit. They sell at least for $300 at Local LFSs. I saw this one on ebay:

Is ther any risk buying these units. Will it be a problem finding replacement filters for them.

Dont buy it! They dont even state what size the filters are or wether it is granulated carbon or not. Stick with a reputible dealer in the aquarium industry like PURELY H2O. You must use 1 micron filters and solid block 1 micron carbon.
