RO/DI systems..... Is one better than another?

[midgetwaiter]

You could add a T to any system and just run that to a water tank for drinking.

Given the local water conditions you should look for a system that has a good membrane in it. Something that does > 95% removal so you don't go through DI resin as fast. It would also be good to invest in something that comes with 1 micron or smaller carbon cartridges as they do a much better job of chloramine removal.
