We too use the reverse osmosis system for all drinking water and foods. Not necessarily because our kids have CF, but because we are picky about the way our water tastes.
We have purchased our latest system off of eBay, but like Jada said you can find them at Home Depot too. It is amazing how used to good tasting water you will get - it's pretty hard to drink just tap water ever again.
