RO/DI Filter

I have decided I should invest in a RO/DI filter and am down to two choices. A Bulk Reef Supply RO/DI 4 stage and an Aquatic Life RO Buddie 3 stage. I can add on the DI to the Aquatic life and that would bring the price to about 80. Does anyone have experience with either one of these? Does the Aquatic Life look good even at a low price? Here are the links:
