    I'm hacker/tinkerer do it looks like an interesting project. Probably pickup a DI system soon. Need to wash windows around the house now, too, and rinsing with DI water it will make things very easy with nothing to wipe or clean for spot-free window panes, especially the high ones and the skylights on the roof.

The RO can actually bring the TDS down to 10-15ppm, which is pretty much bottled water at that point. The order of operation is usually something like-

    carbon block prefilter (coarse) --> carbon block prefilter (fine) --> RO membrane --> DI 1st stage --> DI 2nd stage

    The downside of RO is that it adds complexity, produces waste water (you can use it on your lawn or whatever, though), and also needs to be run at semi-regular intervals to keep from drying out. But if you want hundreds of gallons of 0 tds water per month, that's the way to go. A DI only system makes most sense for the weekend warrior washing a couple of cars per week.
    My homemade system is the configuration you've described... RO first, then DI.

    That is pretty awesome. How much does a decent RO system cost to front-end this rig? I want that, I want that, I want that...
