Any differences, besides cost? I wonder if it will increase my sodium intake a lot. Thanks!
Sodium. Potassium not only cost a lot more, it also should be set up differently than sodium. It is too technical to go through right now (I have to get to my daughters Hockey game), but... potassium is not a good idea in general.

RO water is really nice to drink. Once you try it it is hard to settle for less. I have taste tested my carbon-filtered, softened water against the RO water and it is night and day. RO systems are not that expensive.
It does kind of spoil you. Every once in a while I'll have a fountain soda and taste the chlorine.
