RO/DI Help

Im currently cycling a 65 gallon tank with ro water that i got from a friend. Ive tested my houses water supply and my city water was 286 TDS, but also have a well that i use to water my garden and stuff and that came up as 15 TDS. I can easily hook up my well to a slop sink in my basement. SO my question is when Invest in a RO/DI unit should I hook it up to my city water or well water? Also if I should do well water would i not need as many stages since the input would only be 15 TDS?

I have well water, usually reads 100tds or so, and i use an ro buddie. comes out as 0 tds. I throw a DI on it anyways but it's not needed for the most part. You might need a booster pump but at 15 tds, filters would probably last 1 year plus, i know mine last about that long. You also wouldn't have to worry about chlorine or any other additions the water company might put in there.
 
Well water can have high levels of CO2, which can burn through the DI resin very quickly. If so, I would use the city water. In either case I would get a decent RO/DI unit, and a booster pump if its in the budget.
