try your local water guy kike the culligan man ask about the tds (total desolved solids) the lower the number generaly indicates if he is keeping his units clean and using new resins for the di part

Another good place to look is wine making supply stores. I know a few out this way have pretty sophisticated water purifiers and sell water for a very reasonable price.
