Please don't go the ebay RO/DI route, it will end up biting you guaranteed.
With RO/DI you realy do get what you pay for and a good reef quality system should cost just over $150-$160 complete with a pressure gauge, handheld TDS meter, high quality low micron filters, a name brand 75 GPD Dow Filmtec RO membrane, full size 20 oz vertical refillable DI cartridge and canister and even a bypass valve so you can use RO only or RO/DI.
If its much less than $150 you are giving up something, usually water quality, system quality, filter life or all three.
It pays to shop around but stick with trusted vendors like www.spectrapure.com , www.buckeyefieldsupply.com , www.airwaterice.com , www.purelyh20.com or www.bulkreefsupply.com . Notice all have similar systems at $150-$200 complete, thats really where you want to be. I use only Spectrapure myself but some don't want to spend the extra $$ even though it saves you from then on.
