I have a SpectraPure CSPDI Standard 90-GPD RO/DI System.
No complaints what so ever. Most of the water here comes from local limestone aquifers. So naturally, water out of the tap is liquid rock. After a year of use I still get 0 TDS from this thing. I can't recommend it enough. I originally paid around $240 for it but right now its priced at $189.99
