I will check out ebay and the "AquaFX" $130.00 sounds a whole lot better than 2 or 3 hundred. Thanks Again...You should be able to find a good 3 stage RO unit for less than $200. I got my unit off of a guy on ebay. AquaFX is one of this sites sponsors and they offer RO units aswell. AquaFX has a three stage 50GPD unit for just over $130 after their 10% discount.
